Streaming replication from PostgreSQL to MySQL/MemSQL

Question

I have two database systems currently in use in production: the main PostgreSQL database, and another database ( MemSQL ) used primarily for analytical purposes.

Is there a way to setup streaming replication of some of the tables in PostgreSQL to MemSQL (a MySQL-compatible database) rowstores, assuming the tables on both databases have the same schema?

Answer 1

I do not think that there is a tool for that (yet) but there is one for limited MySQL to Postgres replication:

Maybe this can be adapted to work the other way.

And you could always build your own little data shovel by using the NOTIFY/LISTEN feature of Postgres.
Which is probably only an option if you only have to copy a very simple set of data.
