| Description |
|
In order to be able to convert an expression tree designed to process scalar values into an equivalent tree handling block values we need to have a representation that leads to a better navigation than EExpression. We have already chosen ABT as the format used when producing expression inside $project stage, so we'll have to migrate also the code in sbe_stage_builder_filter.cpp, at least for the $eq, $lt and $gt instructions that are initially targeted by this epic |
