--------------------------------------------------------------
Is it worth shortening the "SSTableReader()" prefix in the message to clean the
messages up a little further? No need for it really. Something like
{code}
StringBuilder ssTableLoggerMsg = new StringBuilder("[");
for (SSTableReader sstr : sstables)
{
ssTableLoggerMsg.append(String.format("%s:level %d, ", sstr.getFilename(),
sstr.getSSTableLevel()));
}
ssTableLoggerMsg.append("]");
{code}

> We should log more information about compactions to be able to debug issues
> more efficiently
> * give each CompactionTask an id that we log (so that you can relate the
> start-compaction-messages to the finished-compaction ones)
> * log what level the sstables are taken from
