_unreachable_endpoints is replicated to call cores. No need to query on
core 0.
This also fixes a bug in storage_proxy::truncate_blocking
which might access _unreachable_endpoints on non-zero cores.
"This series adds two types of functionality to the storage_proxy, it adds the
API that returns the timeout constants from the config and it aligned the
metrics of the read, write and range to origin StorageProxy metrics."
This patch adds the implmentation for the read, write and range
estimated histogram and total latency.
After this patch the following url will be available:
/storage_proxy/metrics/read/estimated_histogram/
/storage_proxy/metrics/read
/storage_proxy/metrics/write/estimated_histogram/
/storage_proxy/metrics/write
/storage_proxy/metrics/range/estimated_histogram/

This patch close the gap between the storage_proxy read, write and range
metrics and the API.
For each of the metrics there will be a histogram, estimated histogram
and total.
The patch contains the definitions for the following:
get_read_estimated_histogram
get_read_latency
get_write_estimated_histogram
get_write_latency
get_range_estimated_histogram
get_range_latency

It uses the gossiper for get cluster name and get partitioner. The

the command would work.

"The snapshots API need to expose GET methods so people can
query information on them. Now that taking snapshots is supported,
this relatively simple series implement get_snapshot_details, a
column family method, and wire that up through the storage_service."
"This patchset implements load_new_sstables, allowing one to move tables inside the
data directory of a CF, and then call "nodetool refresh" to start using them.
Keep in mind that for Cassandra, this is deemed an unsafe operation:
https://issues.apache.org/jira/browse/CASSANDRA-6245
It is still for us something we should not recommend - unless the CF is totally
empty and not yet used, but we can do a much better job in the safety front.
To guarantee that, the process works in four steps:
1) All writes to this specific column family are disabled. This is a horrible thing to
do, because dirty memory can grow much more than desired during this. Throughout out
this implementation, we will try to keep the time during which the writes are disabled
to its bare minimum.
While disabling the writes, each shard will tell us about the highest generation number
it has seen.
2) We will scan all tables that we haven't seen before. Those are any tables found in the
CF datadir, that are higher than the highest generation number seen so far. We will link
them to new generation numbers that are sequential to the ones we have so far, and end up
with a new generation number that is returned to the next step
3) The generation number computed in the previous step is now propagated to all CFs, which
guarantees that all further writes will pick generation numbers that won't conflict with
the existing tables. Right after doing that, the writes are resumed.
4) The tables we found in step 2 are passed on to each of the CFs. They can now load those
tables while operations to the CF proceed normally."
This series adds a histogrm to the column family for live scanned and
tombstone scaned.
It expose those histogram via the API instead of the stub implmentation,
currently exist.
The implementation update of the histogram will be added in a different
series.

Currently, we control incremental backups behavior from the storage service.
This creates some very concrete problems, since the storage service is not
always available and initialized.
The solution is to move it to the column family (and to the keyspace so we can
properly propagate the conf file value). When we change this from the api, we will
have to iterate over all of them, changing the value accordingly.

This adds the implementation that return the estimated total latency of

The histogram that are used typically only sample the data, so to get an
