------------------------------------------
Summary: Provide a method for flushing a CQLSSTableWriter
Key: CASSANDRA-13481
URL: https://issues.apache.org/jira/browse/CASSANDRA-13481
Project: Cassandra
Issue Type: Wish
Reporter: Gabriel Garcia
Priority: Minor
Fix For: 3.11.0
The buffer size estimation in SSTableSimpleUnsortedWriter is not very accurate
and causes OOM errors quite often (or lots of GC pressure) for my specific use
case (rows that vary greatly in # of columns). I guess if the user knows their
data well enough, they can schedule flushes when really needed.
It's just an idea, not sure if flushing would actually help. However, playing
with bufferSizeInMB is not of much help.
