Description

We currently send one frame at a time, which has lots of overhead from TLS handshake, for example. Let's send WAL frames in batches -- perhaps make it configurable and default to 32 KiB (which is 8 frames). We could also make batching smart and send full transactions at at time (or multiple transactions). The server side is built to allow partial transactions to be sent, but sending full transactions has less overhead.

Research direction

No files, tests, or entry points are identified. Start by locating the WAL frame sending path and the server-side handling for partial transactions; done means configurable batching, a 32 KiB default, and support for sending complete transactions or multiple transactions where appropriate.
