| - For taps and targets that _both_ support a common BATCH format (e.g. RDBMS to Warehouse) we have the opportunity to implement 'pass through', whereby records are _never deserialised_ between source to destination, greatly reducing overhead and improving throughput. This would drastically accelerate this common use-case in the singer ecosystem, inspired by the `fast_sync` feature of [Pipelinwise](https://transferwise.github.io/pipelinewise/concept/fastsync.html). |
There was a problem hiding this comment.
Perhaps worth mentioning that, especially when dealing with RDBMS, the COPY command is usually the best way to implement this "pass-through. And the COPY command usually requires csv.
Also, and unrelated: Pipelinwise -> PipelineWise

Really excited for this - it is one of the things which has forced us to go with pure PipelineWise at the moment! |

Draft proposal for BATCH message type support as raised in #2
Rendered SIP Draft: https://github.com/kgpayne/Singer-Working-Group/blob/kp/batch_messages/proposals/draft/SIPXX%20-%20BATCH%20message%20type.md
Note: In order to support discoverability of capabilities like "BATCH" record types, we may require something like #8
