Summary: Calcite engine. Implement correct copy-on-write on schema objects change Key: IGNITE-16395 URL: https://issues.apache.org/jira/browse/IGNITE-16395 Project: Ignite Issue Type: Improvement Reporter: Aleksey Plekhanov Currently, we only copy the schemas list when any schema object changes (see {{{}SchemaHolderImpl.rebuild(){}}}), but it can lead to some problems. For example, during planning, if some index dropped concurrently there will be NPE after {{tbl.getIndex(String)}} in some rules. So, we should copy the table containing this index and copy the schema containing this table at least for DROP INDEX command. -- This message was sent by Atlassian Jira (v8.20.1#820001)
