Customer installs 1.3.0 and has partitioning on, but then needs to purge data from prior to the upgrade. Are the old purge nodes command allowed or how do I do it?
You can change the data retention settings and then do a re-configure. It may take a day or two to reclaim the space because a cronjob controlled by the retention settings must have time to run.
Q. I have 18 months of analytics data (let's pretend) and I install 1.3.0 with a default retention of 12 months. What happens to those last 6 months? Do they get converted to pg_partman and then dropped with the con job runs?
A. Yes but you will have to run the migrate command (opscode-analytics-ctl migrate-partition)
migrate-partition command order of operations:
1) Once the migrate-partition command is run it will move the data
2) Then the cron job setup by the retention configuration will run to drop partitions that are out of the retention setting
