ESQL: Build grouping blocks as Ordinals #114010

Open nik9000 opened 3 days ago

Description

ESQL has support for dictionary encoded blocks of byte valued fields called OrdinalBytesRefBlock. For some of the BlockHash implementations it'd be smaller and faster to build these ordinals blocks most of the time. Specifically the ones that handle a pair or a triple of byte valued columns.

We could also special case Constant blocks too!
