In the current version, you can execute `compress_chunks` on each of the data nodes and enjoy those same savings (and will work transparently with queries, as before).

In subsequent releases, we'll add full support of compression, e.g., just create a compression policy on the access node and you are off and running.

Sounds great. So I just manually execute this `compress_chunks` command once on each data node and then I have compression enabled forever on those nodes?

Not yet, I should have been clearer:

compress_chunk operates on a single chunk, the way to define "compress all chunks older than 1 week is":

   SELECT compress_chunk(i) from show_chunks('conditions', older_than => INTERVAL '1 week');

So you'd need to setup a cron job that runs that script every night or something...at least until we release compression policy support.
