IIRC they have a pretty standard PostGres setup. I'd bet they just setup another PostGres shard replicated just for search, using an extension for the index. Doesn't require the index or working set to be in RAM.

Why do some people write Postgres as PostGres?

Because it's the database that came after Ingres.

Ingres and Postgres/PostgreSQL.

I still don't know /why/ some people say PostGres. I've seen it a few times, on HN and elsewhere, but its wrong isn't it?

Which isn't spelles InGres, is it?

Why do some people call Redis "read-is"? The world may never know...
