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.
