Class Summary

LcsDataWrapper	LcsDataWrapper implements the FarragoMedDataWrapper interface for LucidDB column-store data.
LcsIndexAccessRule	LcsIndexAccessRule is a rule for converting FilterRel+LcsRowScanRel into LcsIndexAccessRel (when the filter has the appropriate form).
LcsIndexAggRel	An aggregate on bitmap data.
LcsIndexAggRule	A rule for directly aggregating off of an unclustered index scan.
LcsIndexBitOpRel	LcsIndexBitOpRel is a base class for implementing bit operation streams with 2 or more inputs
LcsIndexBuilderRel	LcsIndexBuilderRel is a relational expression that builds an unclustered Lcs index.
LcsIndexBuilderRule	LcsModificationRule is a rule for converting an abstract FarragoIndexBuilderRel into a corresponding LcsIndexBuilderRel.
LcsIndexGuide	LcsIndexGuide provides information about the mapping from catalog definitions for LCS tables and their clusters to their Fennel representation.
LcsIndexIntersectRel	LcsIndexIntersectRel is a relation for intersecting the results of two index scans.
LcsIndexMergeRel	LcsIndexMergeRel is a relation for merging the results of an index scan.
LcsIndexMinusRel	LcsIndexMinusRel is a relation for "subtracting" the 2nd through Nth inputs from the first input.
LcsIndexOnlyAccessRule	A rule for converting an LcsRowScanRel(LcsIndexSearchRel) to an LcsIndexOnlyScanRel.
LcsIndexOnlyScanRel	A relation for performing an index only scan of a table (as opposed to performing a regular row scan).
LcsIndexOptimizer	LcsIndexOptimizer optimizes the access path to use index based on cost.

LcsIndexOptimizer.IndexLengthComparator
LcsIndexOptimizer.IndexPageCountComparator
LcsIndexOptimizer.MappedFilterSelectivityComparator

LcsIndexOptimizer.SargColumnFilterSelectivityComparator
LcsIndexSearchRel	LcsIndexSearchRel is a relation for reading from an unclustered index.
LcsIndexSemiJoinRule	LcsIndexSemiJoinRule implements the rule for converting a semijoin expression into the actual operations used to execute the semijoin.
LcsNormalizerRel	A relation which expands bitmap tuples of the form [keys, bitmaps] into repetitious tuples of the form [keys].
LcsRemoveRidExprRule	LcsRemoveRidExprRule is a rule for converting rid expressions that appear in a ProjectRel whose child is a EmptyRel into BIGINT null literals.

LcsSamplingRowScanRel
LcsSamplingRowScanRule	LcsSamplingRowScanRule converts a SamplingRel applied to an LcsRowScanRel into a LcsSamplingRowScanRel.
LcsTable	An implementation of RelOptTable for accessing data in a LucidDB column-store.
LcsTable.ClusterComparator	Comparator that sorts clusters by cluster name.
LcsTableAlterRule	LcsTableAlterRule is a rule for converting an abstract TableModificationRel into a corresponding LcsTableAppendRel in the special case where it is being processed as part of an ALTER TABLE ADD COLUMN statement.
LcsTableAppendRel	LcsTableAppendRel is the relational expression corresponding to appending rows to all of the clusters of a column-store table.
LcsTableAppendRule	LcsTableAppendRule is a rule for converting an abstract TableModificationRel into a corresponding LcsTableAppendRel.
LcsTableDeleteRel	LcsTableDeleteRel is the relational expression corresponding to deletes from a column-store table.
LcsTableDeleteRule	LcsTableDeleteRule is a rule for converting an abstract TableModificationRel into a corresponding LcsTableDeleteRel.
