------------------------------------------
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.
