Member Data Documentation

bool Dbspj::ScanIndexData::m_firstExecution

True if this is the first instantiation of this operation. A child operation will be instantiated once for each batch of its parent.

Definition at line 587 of file Dbspj.hpp.

Uint16 Dbspj::ScanIndexData::m_frags_not_started

The number of fragment for which we have not yet sent SCAN_FRAGREQ but will eventually do so.

Definition at line 575 of file Dbspj.hpp.

Uint32 Dbspj::ScanIndexData::m_largestBatchBytes

Max number of bytes seen in a batch. Used for calculating the number of rows per fragment in the next next batch when using adaptive batch size.

Definition at line 613 of file Dbspj.hpp.

Uint32 Dbspj::ScanIndexData::m_largestBatchRows

Max number of rows seen in a batch. Used for calculating the number of rows per fragment in the next next batch when using adaptive batch size.

Definition at line 608 of file Dbspj.hpp.

IncrementalStatistics Dbspj::ScanIndexData::m_parallelismStat

Mean and standard deviation for the optimal parallelism for earlier executions of this operation.

Definition at line 592 of file Dbspj.hpp.
