    Description

      This error is reported by a InfiniDB user. It should be checked in MariaDB ColumnStore as well.

      "We noticed error occurs when there are two processes attempting to access an infinidb table at the same time:
      Process 1:

      • RENAME TABLE tbl_old to tbl_new;
        Process 2:
      • SELECT * FROM (tbl_old UNION tbl_1 UNION tbl_2)

      This is the error
      DBD::mysql::st execute failed: An unexpected condition within the query caused an internal processing error within InfiniDB. Please check the log files for more details. Additional Information: error in BatchPrimitiveProcessor projectResult. Please check crit.log for more details.

      The crit.log is empty.
