C. Scott Andreas updated CASSANDRA-13481:
-----------------------------------------
Component/s: Libraries
> Provide a method for flushing a CQLSSTableWriter
> ------------------------------------------------
>
> Key: CASSANDRA-13481
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13481
> Project: Cassandra
> Issue Type: Wish
> Components: Libraries
> Reporter: Gabriel Garcia
> Priority: Minor
> Fix For: 4.x
>
>
> 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.
