After repair, the test does a major to compact all sstables into a
single one, so the results can be simply checked by a select from
mutation_fragments() query. Sometimes off-strategy happens parallel to
this major, so after the major there are still 2 sstables, resulting in
the test failing when checking that the query returns just a single row.
To fix, just use tablets for the test table, tablets don't use
off-strategy anymore.

Previously the test test_interrupt_view_build_shard_registration stopped
the node ungracefully and used commitlog periodic mode to persist the
view build progress in a not very reliable way.
It can happen that due to timing issues, the view build progress is not
persisted, or some of it is persisted in a different ordering than
expected.
To make the test more reliable we change it to stop the node gracefully,
so the commitlog is persisted in a graceful and consistent way, without
using the periodic mode delay. We need to also change the injection for
the shutdown to not get stuck.

Run keyspace compaction asynchronously in
`test_tombstone_gc_correctness_during_tablet_split` and only await it
after `split_sstable_rewrite` is disabled.
The problem is that `keyspace_compaction()` starts with a flush, and that
flush can take around five seconds. During that window the split
compaction is stopped before major compaction is retried. The stop aborts
the in-flight major compaction attempt, then the split proceeds far enough
to enter the `split_sstable_rewrite` injection point.
At that point the test used to wait synchronously for major compaction to
finish, but major compaction cannot finish yet: when it retries, it needs
the same semaphore that is still effectively tied up behind the blocked
split rewrite. So the test waits for major compaction, while the split
waits for the injection to be released, and the code that would release
that injection never runs.
Starting major compaction as a task breaks that cycle. The test can first
disable `split_sstable_rewrite`, let the split get out of the way, and
only then wait for major compaction to complete.

This test was observed to fail in CI recently but there is not enough information in the logs to figure out what went wrong. This PR makes a few improvements to make the next investigation easier, should it be needed:
* storage-service: add table name to mutation write failure error messages.
* database: the `database_apply` error injection used to cause trouble, catching writes to bystander tables, making tests flaky. To eliminate this, it gained a filter to apply only to non-system keyspaces. Unfortunately, this still allows it to catch writes to the trace tables. While this should not fail the test, it reduces observability, as some traces disappear. Improve this error injection to only apply to selected table. Also merge it with the `database_apply_wait` error injection, to streamline the code a bit.
* test/test_data_resurrection_in_memtable.py: dump data from the datable, before the checks for expected data, so if checks fail, the data in the table is known.

Previously, all stream-table fixtures in test_streams.py used scope="function",
forcing a fresh table to be created for every test, slowing down the test a bit
(though not much), and discouraging writing small new tests.
This was a workaround for a DynamoDB quirk (that Alternator doesn't have):
LATEST shard iterators have a time slack and may point slightly before the true
stream head, causing leftover events from a previous test to appear in the next
test's reads.
The first two tests in this series fix small problems that turn up once we start
sharing test tables in test_streams.py. The final patch fixes the "LATEST" problem
and enables sharing the test table by using "module" scope fixtures instead of
"function".

blocked the reactor and triggered the CPU stall detector.
This commit fixes the issue by introducing `clone_gently()` to copy the
list elements one by one, and leveraging the existing
`utils::clear_gently()` to destroy them. Both utilize
`seastar::coroutine::maybe_yield()` to allow the reactor to breathe

This series fixes a metrics visibility gap in Alternator and adds regression coverage.
Until now, BatchGetItem and BatchWriteItem updated global latency histograms but did not consistently update per-table latency histograms. As a result, table-level latency dashboards could miss batch traffic.
It updates the batch read/write paths to compute request duration once and record it in both global and per-table latency metrics.
Add the missing tests, including a metric-agnostic helper and a dedicated per-table latency test that verifies latency counters increase for item and batch operations.
This change is metrics-only (no API/behavior change for requests) and improves observability consistency between global and per-table views.

`test_raft_no_quorum.py::test_cannot_add_new_node` is currently flaky in dev
mode. The bootstrap of the first node can fail due to `add_entry()` timing
out (with the 1s timeout set by the test case).
Other test cases in this test file could fail in the same way as well, so we
need a general fix. We don't want to increase the timeout in dev mode, as it
would slow down the test. The solution is to keep the timeout unchanged, but
set it only after quorum is lost. This prevents unexpected timeouts of group0
operations with almost no impact on the test running time.
A note about the new `update_group0_raft_op_timeout` function: waiting for
the log seems to be necessary only for
`test_quorum_lost_during_node_join_response_handler`, but let's do it
for all test cases just in case (including `test_can_restart` that shouldn't

In this series we add support for forwarding strongly consistent CQL requests to suitable replicas, so that clients can issue reads/writes to any node and have the request executed on an appropriate tablet replica (and, for writes, on the Raft leader). We return the same CQL response as what the user would get while sending the request to the correct replica and we perform the same logging/stats updates on the request coordinator as if the coordinator was the appropriate replica.
The core mechanism of forwarding a strongly consistent request is sending an RPC containing the user's cql request frame to the appropriate replica and returning back a ready, serialized `cql_transport::response`. We do this in the CQL server - it is most prepared for handling these types and forwarding a request containing a CQL frame allows us to reuse near-top-level methods for CQL request handling in the new RPC handler (such as the general `process`)
For sending the RPC, the CQL server needs to obtain the information about who should it forward the request to. This requires knowledge about the tablet raft group members and leader. We obtain this information during the execution of a `cql3/strong_consistency` statement, and we return this information back to the CQL server using the generalized `bounce_to_shard` `response_message`, where we now store the information about either a shard, or a specific replica to which we should forward to. Similarly to `bounce_to_shard`, we need to handle this `result_message` in a loop - a replica may move during statement execution, or the Raft leader can change. We also use it for forwarding strongly consistent writes when we're not a member of the affected tablet raft group - in that case we need to forward the statement twice - once to any replica of the affected tablet, then that replica can find the leader and return this information to the coordinator, which allows the second request to be directed to the leader.
This feature also allows passing through exception messages which happened on the target replica while executing the statement. For that, many methods of the `cql_transport::cql_server::connection` for creating error responses needed to be moved to `cql_transport::cql_server`. And for final exception handling on the coordinator, we added additional error info to the RPC response, so that the handling can be performed without having the `result_message::exception` or `exception_ptr` itself.

When computing table sizes via load_stats to determine if a split/merge is needed, we are filtering tablets which are being migrated, in order to avoid counting them twice (both on leaving and pending replica) in the total table size. The tablets are filtered so that they are counted on the leaving replica until the streaming stage, and on the pending replica after the streaming stage.
Currently, the procedure for collecting tablet sizes for load balancing also uses this same filter. This should be changed, because the load balancer needs to have as much information about tablet sizes as possible, and could ignore a node due to missing tablet sizes for tablets in the `write_both_read_new` and `use_new` stages.
For tablet size collection, we should include all the tablets which are currently taking up disk space. This means:
- on leaving replica, include all tablets until the `cleanup` stage
- on pending replica, include all tablets starting with the `write_both_read_new` and later stages
While this is an improvement, it causes problems with some of the tests, and therefore needs to be backported to 2026.1
