Choosing the "right" datastore?

I need recommendation on the datastore to use with Kong, I actually tested postgres and cassandra, but for HA production environment what would you recommend?

We typically see Cassandra used for such requirements, but you can also look into Amazon Aurora’s PostgreSQL.

I would probably decide like this:

Distributed multi-DC: Cassandra
Single DC: PosgreSQL (

I have looked at it’s “extremely” expensive comparing we can run Kong on EC2 for US$36 a month with an amazing rate (t2.medium)…

problem with Aurora PostgreSQL is that the server starts at r4.large and there is nothing “smaller”

That alone without counting with backups, it’s US$150+ monthly …
