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 visualization I believe this way won't block cache. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
