Server's Variable: default_tmp_storage_engine - Documentation Unclear

    XMLWordPrintable

    Details

      Description

      MariaDB "default_tmp_storage_engine" System's Variable is not clear enough.

      • By default it has a value of NULL. ¿What does that mean? ¿That the default server's engine for temporary tables (CREATE TEMPORARY TABLE) is that from "default_storage_engine"? Documentation is not clear enough.
      • Also, when choosing "Memory" Engine for tables created via "CREATE TEMPORARY TABLE", when exceeded "max_heap_table_size", ¿Are tables automatically converted to Aria Engine? (As it happens with internal temporary tables)

        SET @@default_tmp_storage_engine = memory;
        

      Thank you,
      Juan
