What's changed and what's your intention?
Added several utility functions for MapFilterProject:
map
,filter
andproject
to map, filter and project to final output from input columns.compose
to compose two mfp.permute
to rename column indices.evalutate_into
,evaluate_iter
&evaluate_inner
forSafeMfpPlan
to suit different cases for eval mfp.create_from
andevaluate
for MfpPlan which support temproal filter(basically just added some record and remove them after given time)limitations of the current code (optional):
Still far from a complete proof of concept code, lacking reduce operator's code and render dataflow's graph's code
