TDE performance in PostgreSQL

What’s the impact of TDE on performance? People usually quickly throw together a few graphs with basic measurements and treat that as a complete answer, but the question is a bit more complex than that. In this blog post, I’ll try to explain it in a bit more detail: why showcasing a single graph isn’t good for anything other than marketing.

Let me start by making something clear: this is a complex topic, and this will be a long blog post.

pg_tde: our fork is temporary, our commitment to open TDE is not

Recently we noticed a LinkedIn post promoting open_pg_tde, a fork of our pg_tde, claiming to be more open. I looked at the repository, and have to disagree with their claim. In this blog post, I’ll explain why.

The short version: open_pg_tde needs the exact same modified PostgreSQL that pg_tde does – TDE isn’t possible without those upstream changes. The only difference is delivery: they ship those changes as a patch file users have to apply by hand, while we provide a ready-made branch.
