Subject Re: how to organize groups in cluster?
Date Mon, 26 Mar 2018 16:29:29 GMT
Hi Val,
1M per day in memory sales data, 100 parallel financial aggregations in each
batch plus additional  PUB/SUB requests for both instant query and server
push. It has been confirmed to play group count distinct is way too slow, so
we decided to play some of TOP N query in separate domain, for example:

Capture a cache event and export to messaging-->client node subscribe to the
TOPIC-->a IN-MEMORY tree set with particular comparator for filtering and
sorting -->publish result once TOP N map is changed.-->update user

I believe this way won't block cache.
