Uses of StatementBlockRewriteRule in org.apache.sysds.hops.rewrite

Subclasses of StatementBlockRewriteRule in org.apache.sysds.hops.rewrite

Modifier and Type	Class	Description
class	MarkForLineageReuse
class	RewriteCompressedReblock	Rule: Compressed Re block if config compressed.linalg is enabled, we inject compression directions after read of matrices if number of rows is above 1000 and cols at least 1.
class	RewriteForLoopVectorization	Rule: Simplify program structure by pulling if or else statement body out (removing the if statement block ifself) in order to allow intra-procedure analysis to propagate exact statistics.
class	RewriteHoistLoopInvariantOperations	Rule: Simplify program structure by hoisting loop-invariant operations out of while, for, or parfor loops.
class	RewriteInjectOOCTee	This Rewrite rule injects a Tee Operator for specific Out-Of-Core (OOC) patterns where a value or an intermediate result is shared twice.
class	RewriteInjectSparkLoopCheckpointing	Rule: Insert checkpointing operations for caching purposes.
class	RewriteJoinReordering
class	RewriteMarkLoopVariablesUpdateInPlace	Rule: Mark loop variables that are only read/updated through cp left indexing for update in-place.
class	RewriteMergeBlockSequence	Rule: Simplify program structure by merging sequences of last-level statement blocks in order to create optimization opportunities.
class	RewriteRaPushdown	Rule: Simplify program structure by rewriting relational expressions, implemented here: Pushdown of Selections before Join.
class	RewriteRemoveEmptyBasicBlocks	Rule: Simplify program structure by removing empty last-level blocks, which may originate from the original program or due to a sequence of rewrites (e.g., checkpoint injection and subsequent IPA).
class	RewriteRemoveEmptyForLoops	Rule: Simplify program structure by removing empty for loops, which may originate from the sequence of other rewrites like dead-code-elimination.
class	RewriteRemoveForLoopEmptySequence	Rule: Simplify program structure by removing (par)for statements iterating over an empty sequence, i.e., (par)for-loops without a single iteration.
class	RewriteRemoveTransformEncodeMeta	Rule: If transformencode procudes a meta data frame which is never used, flag transformencode to never allocate an serialize this frame.
class	RewriteRemoveUnnecessaryBranches	Rule: Simplify program structure by pulling if or else statement body out (removing the if statement block ifself) in order to allow intra-procedure analysis to propagate exact statistics.
class	RewriteSplitDagDataDependentOperators	Rule: Split Hop DAG after specific data-dependent operators.
class	RewriteSplitDagUnknownCSVRead	Rule: Split Hop DAG after CSV reads with unknown size.
