Add `base64` encoding support for bit & byte vectors at index & query time #111281

Open benwtrent opened 2 months ago

benwtrent commented 2 months ago

Description

We currently support hexidecimal strings & raw byte arrays for indexing and querying bit & byte vectors.

However, adding support for base64 can greatly reduce storage costs. We should consider allowing it as an indexing format, it will make the _source stored and the networking costs much smaller.
