Jordan West updated CASSANDRA-15604: ------------------------------------ Status: Awaiting Feedback (was: Triage Needed) [~omichallat] Could removing cause issues for clients that explicitly state which columns to select (instead of select *)? My concern is that there could be some issues on upgrade for some clients (which we may not have taken as much care to check for during the 2.x -> 3.x changes). Also would https://issues.apache.org/jira/browse/CASSANDRA-14825 address this? > Remove obsolete table/MV options from schema tables > --------------------------------------------------- > > Key: CASSANDRA-15604 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15604 > Project: Cassandra > Issue Type: Improvement > Reporter: Olivier Michallat > Priority: Normal > > CASSANDRA-13910 removed the {{read_repair_chance}} and > {{dclocal_read_repair_chance}} options for tables and materialized views. > CASSANDRA-12868 made {{default_time_to_live}} illegal for materialized views. > However the corresponding columns still exist in {{system_schema.tables}} and > {{system_schema.views}}. Maybe it would make sense to remove them in > Cassandra 4. Historically, obsolete options have been removed in similar > cases, for example {{compaction_strategy_class}}, > {{compaction_strategy_options}} and {{compression_parameters}} were present > in 2.2 but removed in 3.0 (arguably there was also a major refactoring of > schema tables during that transition). > This is not a huge deal, but it would make things a bit easier for the Java > driver (our metadata exposes a "client-side describe" feature, and currently > we assume that any column in the schema table must be added to the CREATE > TABLE statement). -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
