Examples with IFrameOperationCallback org.apache.hyracks.storage.am.lsm.common.api.IFrameOperationCallback used on opensource projects

Example 1 with IFrameOperationCallback

use of org.apache.hyracks.storage.am.lsm.common.api.IFrameOperationCallback in project asterixdb by apache.

the class LSMPrimaryUpsertOperatorNodePushable method open.

// we have the permutation which has [pk locations, record location, optional:filter-location]
// the index -> we don't need anymore data?
// we need to use the primary index opTracker and secondary indexes callbacks for insert/delete since the lock would
// have been obtained through searchForUpsert operation
