Examples of TDelete

org.apache.hadoop.hbase.thrift2.generated.TDelete

Used to perform Delete operations on a single row. The scope can be further narrowed down by specifying a list of columns or column families as TColumns. Specifying only a family in a TColumn will delete the whole family. If a timestamp is specified all versions with a timestamp less than or equal to this will be deleted. If no timestamp is specified the current time will be used. Specifying a family and a column qualifier in a TColumn will delete only this qualifier. If a timestamp is specified only versions equal to this timestamp will be deleted. If no timestamp is specified the most recent version will be deleted. To delete all previous versions, specify the DELETE_COLUMNS TDeleteType. The top level timestamp is only used if a complete row should be deleted (i.e. no columns are passed) and if it is specified it works the same way as if you had added a TColumn for every column family and this timestamp (i.e. all versions older than or equal in all column families will be deleted)

    columnValues.add(new TColumnValue(wrap(familyAname), wrap(qualifierAname), wrap(valueAname)));


    List<TColumnIncrement> incrementColumns = new ArrayList<TColumnIncrement>();
    incrementColumns.add(new TColumnIncrement(wrap(familyAname), wrap(qualifierAname)));


    TDelete tDelete = new TDelete(wrap(rowName));
    tDelete.setDurability(TDurability.SKIP_WAL);
    Delete delete = deleteFromThrift(tDelete);
    assertEquals(delete.getDurability(), Durability.SKIP_WAL);


    tDelete.setDurability(TDurability.ASYNC_WAL);
    delete = deleteFromThrift(tDelete);
    assertEquals(delete.getDurability(), Durability.ASYNC_WAL);


    tDelete.setDurability(TDurability.SYNC_WAL);
    delete = deleteFromThrift(tDelete);
    assertEquals(delete.getDurability(), Durability.SYNC_WAL);


    tDelete.setDurability(TDurability.FSYNC_WAL);
    delete = deleteFromThrift(tDelete);
    assertEquals(delete.getDurability(), Durability.FSYNC_WAL);


    TPut tPut = new TPut(wrap(rowName), columnValues);
    tPut.setDurability(TDurability.SKIP_WAL);
