> 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.
