> It's possible right now to insert values that cannot be flushed. If a column is configured to be compressed, the block compressor will limit blocks to 16MB so if a large value isn't compressible, it won't be flushable. It will show up like this in the log:
> {noformat}
> Invalid argument: Flush to disk failed: estimated max size 29545252 is greater than the expected 16777216
> {noformat}
> Once this happens it's impossible to bring the server back since it will bootstrap the tablet, try flushing again, and crash.
