Stefan Miklosovic commented on CASSANDRA-18102:
-----------------------------------------------
This ticket is easy to do but I think it will not be optimal. Currently, upon
every SELECT statement, we would need to load all snapshots all over again and
again from disk because SnapshotManager is holding only expired ones.
> Add a virtual table to list snapshots

> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/Virtual Tables, Local/Snapshots
> Reporter: Paulo Motta
> Assignee: maxwellguo
> Priority: Normal
>
> It should be possible to query a node's snapshots via virtual tables.
> The table should expose the same fields/columns as the
> [TableSnapshot|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/service/snapshot/TableSnapshot.java]
> class.
> Something along these lines:
> {noformat}
> cqlsh> SELECT * FROM system_views.snapshots;
>
> tag | keyspace_name | table_name | table_id | is_ephemeral | created_at |
> expires_at | directories
