Method Detail

isRestrictedSubScan

boolean isRestrictedSubScan()

Whether this subscan is a restricted (skip) subscan

Returns:

true if this subscan is a restricted subscan, false otherwise

addJoinForRestrictedSubScan

void addJoinForRestrictedSubScan(RowKeyJoin batch)

For a restricted sub-scan, this method allows associating a rowkey join instance. A subscan within a minor fragment must have a corresponding rowkey join batch instance from which it will retrieve its set of rowkeys to perform the restricted scan.

Parameters:

batch -
