Introducing WAL-G: Faster Disaster Recovery for Postgres

Neat. My concern out of the gate is what would be the perf hit.

I assume I am switching from WAL-E to WAL-G for more perf. But WAL-E speaks GCS. If WAL-G needs an extra hop to do so, may lose some of the point of it..

Yeah, no idea personally. Haven't used the gateway functionality in Minio at all.

That being said, the Minio team seem pretty good with writing performance optimised code. Frank Wessels (on Minio team), has been writing articles about Go assembler and other Go optimisation things recently. eg:

• https://blog.minio.io/accelerating-blake2b-by-4x-using-simd-...

• https://blog.minio.io/golang-internals-part-2-nice-benefits-...

So the performance impact might not be such a problem. :)
