  • Constructor Details

    • AdminRepairTableRequest

      public AdminRepairTableRequest()
      Constructs an AdminRepairTableRequest object with default parameters.
    • AdminRepairTableRequest

      public AdminRepairTableRequest(List<String> tableNames, Map<String,String> tableTypes, Map<String,String> options)
      Constructs an AdminRepairTableRequest object with the specified parameters.
      Parameters:
      tableNames - List of tables to query. An asterisk returns all tables.
      tableTypes - ID of the type per table.
      options - Optional parameters.
      • REPAIR_POLICY: Corrective action to take. Supported values:
        • DELETE_CHUNKS: Deletes any corrupted chunks.
        • SHRINK_COLUMNS: Shrinks corrupted chunks to the shortest column.
        • REPLAY_WAL: Manually invokes write-ahead log (WAL) replay on the table.
        • ALTER_TABLE: Reset columns modification after incomplete alter column.
        • RESYNC_REPLICAS: Repairs replicated tables whose record counts differ across the worker ranks and toms: the copy with the most records is kept, and every other copy is replaced with it. That copy may include records from a load that did not complete, or records that a delete did not remove. A table whose copies all have the same number of records is not repaired, even if their contents differ. Views cannot be named in tableNames; a named table that is not replicated is reported in repairStatus. An asterisk selects every replicated table. The repair runs only while no other requests are running. The repaired tables are listed in the REPAIRED_REPLICATED_TABLES entry of the response info map.
      • VERIFY_ALL: If FALSE only table chunk data already known to be corrupted will be repaired. Otherwise the database will perform a full table scan to check for correctness. Supported values:The default value is FALSE.
      The default value is an empty Map.
