Detailed Description

The top class package of Nested Loop Join providing a "join function".

Note: Just single thread, the threads parameter is useless

Member Function Documentation

◆ join() [1/4]

virtual size_t INTELLI::NestedLoopJoin::join	(	TuplePtr *	ts,
		TuplePtr *	tr,
		size_t	tsLen,
		size_t	trLen,
		int	threads = `1`
	)

virtual

The function to execute join, legacy way.

Parameters

ts	The tuples of stream S, legacy pointer
tr	The tuples of stream R, legacy pointer
tsLen	The length of S
trLen	The length of R
threads	The parallel threads

Returns: The joined tuples

Warning: This is a legacy function, avoid using it if possible

Reimplemented from INTELLI::AbstractJoinAlgo.

◆ join() [2/4]

virtual size_t INTELLI::NestedLoopJoin::join	(	TuplePtr *	ts,
		TuplePtr	tr,
		size_t	tsLen,
		int	threads = `1`
	)

virtual

The function to execute join, batch of one, tuple of another.

Parameters

ts	The tuples of stream S, legacy pointer
tr	The tuples of stream R, one tuple
tsLen	The length of S
threads	The parallel threads

Returns: The joined tuples

Warning: This is a legacy function, avoid using it if possible

Reimplemented from INTELLI::AbstractJoinAlgo.

◆ join() [3/4]

virtual size_t INTELLI::NestedLoopJoin::join	(	TuplePtrQueue	ts,
		TuplePtr	tr,
		int	threads = `1`
	)

virtual

The function to execute join, batch of one, tuple of another.

Parameters

ts	The tuples of stream S
tr	The tuple of stream R
threads	The parallel threads

Returns: The joined tuples

Reimplemented from INTELLI::AbstractJoinAlgo.

◆ join() [4/4]

virtual size_t INTELLI::NestedLoopJoin::join	(	TuplePtrQueue	ts,
		TuplePtrQueue	tr,
		int	threads = `1`
	)

virtual

The function to execute join, batch of both.

Parameters

ts	The tuples of stream S
tr	The tuples of stream R
threads	The parallel threads

Returns: The joined tuples

Todo:: Add AMP and NUMA support in the future, so far only generic SMP

Reimplemented from INTELLI::AbstractJoinAlgo.
