Parallelize file/block metadata loading for tables with large number of partitions

    XMLWordPrintableJSON

    Details

      Description

      Currently, loading file/block metadata of a table is performed by a single thread. For large tables, loading metadata may take a long time, thereby increasing the latency during planning and/or other DDL/DML operations. We should consider parallelizing this process.
