Although I have done many more benchmark testing against other databases for query speeds; I haven't noticed any significant speed degradation on writes.
Could you clarify what you mean by 'this limits your write capabilities'?
> W.r.t. query speeds on your columnar storage engine, you will obviously have much better writes that row oriented storage engines.
This should have said reads, not writes. Columnar storage takes significantly more effort to handle writes because it must do many more IOs across the different columns, potentially more de/compression cycles, etc.
