a009644c7d raft_topology, tablets: Drain tablets in parallel with other topology operations
Allows other topology operations to execute while tablets are being
drained on decommission. In particular, bootstrap on scale-out. This
is important for elasticity.

Allows multiple decommission/removenode to happen in parallel, which
is important for efficiency.

Flow of decommission/removenode request:
  1) pending and paused, has tablet replicas on target node.
     Tablet scheduler will start draining tablets.
  2) No tablets on target node, request is pending but not paused
  3) Request is scheduled, node is in transition
  4) Request is done

Nodes are considered draining as soon as there is a leave or remove
request on them. If there are tablet replicas present on the target
node, the request is in a paused state and will not be picked by
topology coordinator. The paused state is computed from topology state
automatically on reload.

When request is not paused, its execution starts in
write_both_read_old state. The old tablet_draining state is not
entered (it's deprecated now).

Tablet load balancing will yield the state machine as soon as some
request is no longer paused and ready to be scheduled, based on
standard preemption mechanics.

The test case test_explicit_tablet_movement_during_decommission is
removed. It verifies that tablet move API works during tablet draining
transition. After this PR, we no longer enter this transition, so the
test doesn't work. It loses its purpose, because movement during
normal tablet balancing is not special and tested elsewhere.

d3ee82ea51 topology_coordinator, storage_service: Validate node removal/decommission at request submission time
After parallel tablet draining, the validation at the time request
starts executing is too late, tablets will be already drained.

This trips tests which expect validation failure, but get tablet
draining failure instead.

Also, in case of decommission, it's a waste to go through draining
only to discover that the operation has to be rolled back due to
validation.

So avoid submitting a request altogether if it's invalid.
The validation at request execution start remains, for extra sefety.

validate_removing_node() was extracted out of topology_coordinator,
so that it can be called by storage_service on non-coordinator.

Some tests need adjusting for the fact that after failed removenode
the node may still not be marked as excluded, so we need to explicitly
exclude it or add to the list of ignored nodes in the next removenode
operation.

34d28475d9 Merge 'Implement Vector Search filtering API' from Dawid Pawlik
Since Vector Store service filtering API has been implemented (scylladb/vector-store#334), there is a need for the implementation of Scylla side part.
This patch should implement a `statement_restrictions` parsing into Vector Store filtering API compatible JSON objects.
Those objects should be added to ANN query vector POST requests as `filter` object.

After this patch, the subset of all operations ([Vector Search Filtering Milestone 1](https://scylladb.atlassian.net/wiki/spaces/RND/pages/156729450/Vector+Search+Filtering+Design+Document#Milestone-1)) happy path should be completed, allowing users to filter on primary key columns with single column `=` and `IN` or multiple column `()=()` and `() IN ()`.
The restrictions for other operations should be implemented in a PR on Vector Store service side.

---

This PR implements parsing the `statement_restrictions` into Vector Store filtering API compatible JSON objects.
The JSON objects are created and used in ANN vector queries with filtering.
It closes the Scylla side implementation of Vector Search filtering milestone 1.

Unit tests for `statement_restrictions` parsing are added. Integration tests will be added on Vector Store service side PR.

1e09a34686 replica: add abort polling to memtable and cache readers
Continuing the read once it is aborted (e.g. due to timeout) is a waste
of resources, as the produced results will be discarded.
Poll the permit's abort exception in the memtable and cache reader's
fill_buffer(). This results in one poll per buffer filled (8KB of data).

We already have similar poll for sstable readers, as disk reads are
usually much heavier and therefore it is more important to stop them
ASAP after abort. Cache and memtable reads are usually quick but not
always, hence it is important to also have polling in the cache and
memtable readers.

eb7be9010d Merge 'topology_coordinator: Refresh load stats after table is created or altered' from Tomasz Grabiec
We switched to the size-based load balancing, which now has more
strict requirements for load stats. We no longer need only per-node
stats, but also per-tablet stats.

Bootstrapping a node triggers stats refresh, but allocating tablets on
table creation didn't. So after creating a table, load balancer
couldn't make progress for up to 60s (stats refresh period).

This makes tests take longer, and can even cause failures if tests are
using a low-enough timeout.

eef798d84f Merge 'Distribute data evenly among primary replicas during restore' from Robert Bindar
Most likely 817fdad uncovered the fact that our choice of primary replica was resonating with tablet allocation and we were ending up picking the same replica as primary within a scope instead of rotating primaryship among all replicas in the scope.
This created situations where for instance, restoring into a 9 nodes with primary_replica_only=true would put all data into 3 nodes, leaving the other 6 unused. The balancing of the dataset was performed by the subsequent repair step.

This PR fixes this by changing the formula for picking up the primary replica out of a set of eligible replicas from within the passed scope.
The PR also extends the testing scenarios in `test_backup.py` so we get to run restore for a set of topologies, for all combinations of scope, primary_replica_only and min_tablet_counts.
Most of the work was done by @bhalevy [here](https://github.com/scylladb/scylladb/compare/master...bhalevy:scylla:load-balance-primary-replica), this PR just splitted it and did touchups here and there.

    aws_region: us-east-1
```

fixes: #26570

This is 2nd attempt, previous one (#27360) was reverted because it reported endpoint configs in new format via API and CQL always, even if the endpoint was configured in the old way. This "broke" scylla manager and some dtests. This version has this bug fixed, and endpoints are reported in the same format as they were configured with.

About correctness of the changes.

No modifications to existing tests are made here, so old format is respected correctly (as far as it's covered by tests). To prove the new format works the the test_get_object_store_endpoints is extended to validate both options. Some preparations to this test to make this happen come on their own with the PR #28111  to show that they are valid and pass before changing the core code.

Enhancing the way configuration is made, likely no need to backport.

d919aacc69 storage_proxy: mark write_timeouts metric for counter write timeouts
When a counter write times out (due to rpc::timeout_error or timed_out_error),
the code was throwing mutation_write_timeout_exception but not marking the
write_timeouts metric. This resulted in counter write timeouts not being
counted in the scylla_storage_proxy_coordinator_write_timeouts metric.

Regular writes go through mutate_internal -> mutate_end, which catches
mutation_write_timeout_exception and marks the metric. However, counter
writes use a separate code path (mutate_counters) that has its own
exception handling but was missing the metric update.

This fix adds get_stats().write_timeouts.mark() before throwing the
timeout exception in the counter write path, consistent with how the
CAS path handles cas_write_timeouts.

bee5f63cb6 topology coordinator: complete pending operation for a replaced node
A replaced node may have pending operation on it. The replace operation
will move the node into the 'left' state and the request will never be
completed. More over the code does not expect left node to have a
request. It will try to process the request and will crash because the
node for the request will not be found.

The patch checks is the replaced node has peening request and completes
it with failure. It also changes topology loading code to skip requests
for nodes that are in a left state. This is not strictly needed, but
makes the code more robust.

6b5923c64e test: test_group0_schema_versioning: wait for schema sync in system.local
`test_schema_versioning_with_recovery` is currently flaky. It performs
a write with CL=ALL and then checks if the schema version is the same on
all nodes by calling `verify_table_versions_synced`. All nodes are expected
to sync their schema before handling the replica write. The node in
RECOVERY mode should do it through a schema pull, and other nodes should do
it through a group 0 read barrier.

The problem is in `verify_local_schema_versions_synced` that compares the
schema versions in `system.local`. The node in RECOVERY mode updates the
schema version in `system.local` after it acknowledges the replica write
as completed. Hence, the check can fail.

We fix the problem by making the function wait until the schema versions
match.

Note that RECOVERY mode is about to be retired together with the whole
gossip-based topology in 2026.2. So, this test is about to be deleted.
However, we still want to fix it, so that it doesn't bother us in older
branches.

122b7847e5 Merge 'index: Accept view properties in CREATE INDEX' from Dawid Mędrek
Problem
-------
Secondary indexes are implemented via materialized views under the
hood. The way an index behaves is determined by the configuration
of the view. Currently, it can be modified by performing the CQL
statement `ALTER MATERIALIZED VIEW` on it. However, that raises some
concerns.

Consider, for instance, the following scenario:

1. The user creates a secondary index on a table.
2. In parallel, the user performs writes to the base table.
3. The user modifies the underlying materialized view, e.g. by setting
   the `synchronous_updates` to `true` [1].

Some of the writes that happened before step 3 used the default value
of the property (which is `false`). That had an actual consequence
on what happened later on: the view updates were performed
asynchronously. Only after step 3 had finished did it change.

Unfortunately, as of now, there is no way to avoid a situation like
that. Whenever the user wants to configure a secondary index they're
creating, they need to do it in another schema change. Since it's
not always possible to control how the database is manipulated in
the meantime, it leads to problems like the one described.

That's not all, though. The fact that it's not possible to configure
secondary indexes is inconsistent with other schema entities. When
it comes to tables or materialized views, the user always have a means
to set some or even all of the properties during their creation.

Solution
--------
The solution to this problem is extending the `CREATE INDEX` CQL
statement by view properties. The syntax is of form:

```
> CREATE INDEX <index name>
> .. ON <keyspace>.<table> (<columns>)
> .. WITH <properties>
```

where `<properties>` corresponds to both index-specific and view
properties [2, 3]. View properties can only be used with indexes
implemented with materialized views; for example, it will be impossible
to create a vector index when specifying any view property (see
examples below).

When a view property is provided, it will be applied when creating the
underlying materialized view. The behavior should be similar to how
other CQL statements responsible for creating schema entities work.

High-level implementation strategy
----------------------------------
1. Make auxiliary changes.
2. Introduce data structures representing the new set of index
   properties: both index-specific and those corresponding to the
   underlying view.
3. Extend `CREATE INDEX` to accept view properties.
4. Extend `DESCRIBE INDEX` and other `DESCRIBE` statements to include
   view properties in their output.

User documentation is also updated at the steps to reflect the
corresponding changes.

Implementation considerations
-----------------------------
There are a number of schema properties that are now obsolete. They're
accepted by other CQL statements, but they have no effect. They
include:

* `index_interval`
* `replicate_on_write`
* `populate_io_cache_on_flush`
* `read_repair_chance`
* `dclocal_read_repair_chance`

If the user tries to create a secondary index specifying any of those
keywords, the statement will fail with an appropriate error (see
examples below).

Unlike materialized views, we forbid specifying the clustering order
when creating a secondary index [4]. This limitation may be lifted
later on, but it's a detail that may or may not prove troublesome. It's
better to postpone covering it to when we have a better perspective on
the consequences it would bring.

Examples
--------
Good examples
```
> CREATE INDEX idx ON ks.t (v);
> CREATE INDEX idx ON ks.t (v) WITH comment = 'ok view property';
> CREATE INDEX idx ON ks.t (v)
  .. WITH comment = 'multiple view properties are ok'
  .. AND synchronous_updates = true;
> CREATE INDEX idx ON ks.t (v)
  .. WITH comment = 'default value ok'
  .. AND synchronous_updates = false;
```

Bad examples
```
> CREATE INDEX idx ON ks.t (v) WITH replicate_on_write = true;

SyntaxException: Unknown property 'replicate_on_write'

> CREATE INDEX idx ON ks.t (v)
  .. WITH OPTIONS = {'option1': 'value1'}
  .. AND comment = 'some text';

InvalidRequest: Error from server: code=2200 [Invalid query]
  message="CUSTOM index requires specifying the index class"

> CREATE INDEX idx ON ks.t (v) WITH CLUSTERING ORDER BY (v ASC);

```

and so on. For more examples, see the relevant tests.

1e37781d86 schema: Add initializer for compression defaults
In PR 5b6570be52 we introduced the config option
`sstable_compression_user_table_options` to allow adjusting the default
compression settings for user tables. However, the new option was hooked
into the CQL layer and applied only to CQL base tables, not to the whole
spectrum of user tables: CQL auxiliary tables (materialized views,
secondary indexes, CDC log tables), Alternator base tables, Alternator
auxiliary tables (GSIs, LSIs, Streams).

Fix this by moving the logic into the `schema_builder` via a schema
initializer. This ensures that the default compression settings are
applied uniformly regardless of how the table is created, while also
keeping the logic in a central place.

Register the initializer at startup in all executables where schemas are
being used (`scylla_main()`, `scylla_sstable_main()`, `cql_test_env`).

Finally, remove the ad-hoc logic from `create_table_statement`
(redundant as of this patch), remove the xfail markers from the relevant
tests and adjust `test_describe_cdc_log_table_create_statement` to
expect LZ4WithDicts as the default compressor.

Fixes #26914.

76b2d0f961 db: config: Add accessor for sstable_compression_user_table_options
The `sstable_compression_user_table_options` config option determines
the default compression settings for user tables.

In patch 2fc812a1b9, the default value of this option was changed from
LZ4 to LZ4WithDicts and a fallback logic was introduced during startup
to temporarily revert the option to LZ4 until the dictionary compression
feature is enabled.

Replace this fallback logic with an accessor that returns the correct
settings depending on the feature flag. This is cleaner and more
consistent with the way we handle the `sstable_format` option, where the
same problem appears (see `get_preferred_sstable_version()`).

As a consequence, the configuration option must always be accessed
through this accessor. Add a comment to point this out.

In patches 11f6a25d44 and 7b9428d8d7 we added tests to verify that
auxiliary tables for both CQL and Alternator have the same default

where these defaults originate from; they just verify that they are
consistent.

Add some more tests to verify the actual source of the defaults, which
is expected to be the `sstable_compression_user_table_options`
from the configuration. Unlike the previous tests, these tests require
dedicated Scylla instances with custom configuration, so they must be
placed under `test/cluster/`.

63b9a7e2b5 test: pylib: log_browsing: Grep logs without considering newly appended lines
At the end of the test case, the framework greps logs for errors and
backtraces. The servers are still running at this point. Some test
cases enable debug-level logging. If servers manage to produce new
lines between the python script processes them, the grep will never
return.

Protect against this by grepping over a file snapshot.

Fixes #28086

9c627bc44a test: Split the object_store/test_get_object_store_endpoints test
It tests two things -- the way object storage config is represented via
API and CQL (from sytem.config) and that updating config affects CREATE
KEYSPACE CQL (with keyspace storage options)

It's better to split the test, as its former part is going to be
extented to validate old/new config formats (see #26570)

db13ece9a0 test: Refactor restoring code in test_backup to match SM pattern
This patch refactors the restoring code in cluster/test_backup.py
so it matches better the way SM works.
The patch also refactors test_restore_with_streaming_scopes so to
facilitate running restore scenarios under all supported scopes
with or w/o primary_replica_only enabled by reusing the servers
and backups for a topology. This allows us to test a lot more scenarios
without making the test impossibly slow.

2a831ad373 Merge 'Address CodeQL Errors' from Botond Dénes
Address all errors reported by CodeQL as reported on https://github.com/scylladb/scylladb/security/quality.
This is a mixed bag, with some harmless issues, while others are severe problems which will result in the code breaking (if it is even run). I suspect some of the more severe problems were found in dead code that is not used at all -- hence nobody noticed.
Still, these issues are good to fix, so we can reduce noise in the reports and improve the maintainability of the code.

Code cleanup, no backport

609b283d98 test/cqlpy: add another reproducer for known issue
This patch adds a second reproducer for issue #25839, which is about
scanning a secondary index which returns partial results. The new test
uses count(*) without requesting the row themselves, but still has the
same problem of counting only part of the rows. This is the problem that
a user reported in issue #28026.

Unlike the previous test, this test works correctly on older versions
of Scylla - by using larger data, like on Cassandra - without changing
a configuration variable that did not yet exist. So with this test we
can confirm that this bug is a Scylla 5.2 regression:

  test/cqlpy/run --release 5.1 test_secondary_index.py::test_short_count

passes, while

  test/cqlpy/run --release 5.2 test_secondary_index.py::test_short_count

fails. It also fails on master, so the new test is marked "xfail".

354c805e6a reader_permit: remove check_abort()
This method can cause performance regressions if used in the wrong place
-- namely if it is used to abort reads by throwing the abort exception.
Exceptions should be propagated during reads without throwing them,
otherwise they cause extra CPU load, making a bad situation worse.
Remove this method, so it doesn't accidentally get more users, migrate
remaining users to get_abort_exception().

a0ddac655d test/boost/database_test: add test for read timeout exceptions
Read timeouts shouldn't trigger exceptions thrown, exceptions should be
solely propagated via futures, otherwise they put extra strain on the
system at the worst possible time: when it is overload already enough
that reads started to time out.
The test covers both single partition reads and full scans, with two
scenarios:
* timeout while the read is queued
* timeout when the read is already ongoing

34191d8fd4 alternator: fix signature checking of headers with multiple spaces
We have a test in test_compressed_response.py that reproduces a bug
where in Alternator's signature checking code, if a header had multiple
consecutive spaces its signature isn't checked correctly.

This patch fixes this and that xfailing test begins to pass.

But it turns out that the handling of multiple consecutive spaces in
headers when calculating the authentication signature is just one example
of "header canonization" that the AWS Signature V4 specification requires
us to do. There are additional types of header canonization that Alternator
must do, and this patch also adds new tests in test_authorization.py for
checking *all* the types of canonization.

Fortunately, for all other types of canonizations, we already handled
them correctly - Alternator already lowercases header names, sorts them
alphabetically and removes leading and trailing spaces before calculating
the signature. So most of the new tests added pass also without this patch,
and only one of them, test_canonization_middle_whitespace, needs this
patch to pass. As usual, all the new tests also pass on DynamoDB.

To fix the problem, we need to remove the first, redundant definition of

(lines 25-40) should be retained as it has more substantial test logic.
No other code changes or imports are needed, as the test logic is
preserved fully in the retained definition.

66aee0fb5e alternator: add optional listeners for proxy protocol v2
Following 954f2cbd2f, which added proxy protocol v2 listeners
for CQL, we do the same for alternator. We add two optional ports
for plain and TLS-wrapped HTTP.

We test each new port, that the old ports still work, and that
mixing up a port with no proxy protocol and a connection with proxy
protocol (or the opposite) fails. The latter serves to show
that the testing strategy is valid and doesn't just pass whatever
happens. We also verify that the correct addresses (and TLS mode)
show up in system.clients.
