Field Detail

id

public long id

Modifying this variables or adding new ones should be done in sync with the static methods compactionStructToInfo() and compactionInfoToStruct(). This class is going to be deserialized and serialized so missing this may result in the value of the field being resetted. This will be fixed at HIVE-21056.

dbname

public String dbname

tableName

public String tableName

partName

public String partName

state

public char state

type

numberOfBuckets

public int numberOfBuckets

orderByClause

public String orderByClause

minOpenWriteTxnId

public long minOpenWriteTxnId

highestWriteId

public long highestWriteId

The highest write id that the compaction job will pay attention to. 0 means it wasn't set (e.g. in case of upgrades, since ResultSet.getLong() will return 0 if field is NULL) See also TxnUtils.createValidCompactWriteIdList(TableValidWriteIds) and ValidReaderWriteIdList.highWatermark.
