This patchset is the first part of the series implementing
BlockMapJoinCoreMKQL callable. This part implementsBlockMapJoinCorecomputation node for the join types, that don't require "dict" payload (i.e.LeftSeimandLeftOnly), so MKQL version is bumped either. The support for otherMapJoinCoretypes are implemented in scope of the next PRs.By the way the new flag is added to
ValidateBlock*Typehelpers to control whether the resulting item types are block or "raw" (i.e. unwrapped).Changelog category
