I've been pumping billions of records into a single topic in a MapR-Stream daily for close to a year now, and I'm noticing that the region count keeps going up and up and up. It has 5,584 regions now.
I regularly call the purge endpoint and have a 4 day TTL on messages. The size of the stream seems to keep pretty constant at 700GB physical size, 29.6 TB logical size.
Why does the stream keep getting more regions in it!? Is this a problem? Most of the regions have a very small physical size and no rows at this point.
