DeltaMetaData

public DeltaMetaData()

DeltaMetaData

public DeltaMetaData(long minWriteId,
                     long maxWriteId,
                     List<Integer> stmtIds,
                     long visibilityTxnId,
                     List<AcidInputFormat.DeltaFileMetaData> deltaFiles)

Parameters:

minWriteId - min writeId of the delta directory

maxWriteId - max writeId of the delta directory

stmtIds - delta dir suffixes when a single txn writes > 1 delta in the same partition

visibilityTxnId - maybe 0, if the dir name didn't have it. txnid:0 is always visible

deltaFiles - bucketFiles in the directory
