![]() ![]() ![]() You don't want to do that because it's not necessary to restart all 66 nodes. No, you can only disable auto_snapshot in cassandra.yaml which requires a rolling restart.By truncating first, it would allow the DROP to work without issues. This wouldn't result in a schema disagreement since it doesn't change the schema. I'd recommend truncating the tables first as above.These repositories are real Git repositories but you can view them in the Keybase app. You can put any kind of content in these repositories, but they’re especially useful for personal private repos or for secret content shared among teams. And yes, it's a combination of (a) data size and (b) number of nodes. Keybase supports free, encrypted, authenticated, and private Git repositories. You can run into timeouts and schema disagreement.Manually delete snapshots from filesystem as necessary.Repeat the steps above until all tables are dropped. ![]() This means anything that Keybase holds is nearly impossible to decrypt (even if the servers are hacked). Check for schema disagreement and fix as appropriate Keybase is an all in one place for team collaboration similar to Slack, cloud storage with up to 250GB of free space, a git version control system and a cryptocurrency wallet (stellar lumens) all with the power of 256-bit encryption technology.Wait at least 1 minute for schema to propagate.If the TRUNCATE times out, attempt a second time.Due to (a) size of the data and (b) number of nodes, my approach would be: The only real issue I can foresee you would run into is a schema disagreement. From each node delete the data directory for the keyspace (data is already backed up somewhere, there is no need of autosnapshot) nodetool describecluster, check for any inconsistenciesĮ. drop keyspace using cqlsh (with request-timeout=600)ĭ. drop tables using cqlsh (with request-timeout=600)Ĭ. Any considerations before/after dropping the tables/keyspace? here are the steps I am going to follow -ī.Is there any way to disable auto_snapshot at session level or from a driver level for specific tables or keyspace?.Other than dropping tables and then keyspace is there any other way to safely drop the keyspace? For example would dropping the sstables from nodes make drops quick and smoother? Would dropping sstables trigger repairs/compactions and cause any issues?.When dropping tables and keyspace on this cluster - what might cause issues? the size of the unused keyspace (55tb) or the number of nodes (66) in the cluster to which the schema change (drop tables/keyspace) would would need to be propagated?.Want to drop the keyspace/tables to reclaim space without causing any issues in the cluster? The keyspace has 3 tables in it and there are no reads/writes on the tables since last one month. There is a keyspace occupying 55tb of space, cluster has 66 nodes in it (dse 5.1.6, cassandra 3.11) ![]()
