Hi guys,
I run a cluster with 5 nodes, cassandra version 3.0.5.
I get this warning:
2016-09-28 17:22:18,480 BigTableWriter.java:171 - Writing large partition...
for some materialized view. Some have values over 500MB. How this affects
performance? What can/should be done? I suppose is a problem
Hi Robert,
Materialized Views are regular C* tables underneath, so based on their PK
they can generate big partitions.
It is often advised to keep partition size under 100MB because larger
partitions are hard to read and compact. They usually put pressure on the
heap and lead to long GC pauses +
Thanks!
