[jira] [Created] (IGNITE-11223) SQL: Merge "collectCacheIds" and "processCaches" methods

Vladimir Ozerov created IGNITE-11223:
----------------------------------------

             Summary: SQL: Merge "collectCacheIds" and "processCaches" methods
                 Key: IGNITE-11223
                 URL: https://issues.apache.org/jira/browse/IGNITE-11223
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Vladimir Ozerov


Both methods are essentially two pieces of the same process - collect cache IDs for the given query, check MVCC mode. But because they are separated, we have unnecessary collection copies, "isEmpty" checks and iterations. 

Provided that these methods are on a hot path, let's merge them accurately.
