> The performance of RocksDb without any record cache is slightly better than
> with the default of 10MB of the default cache. This needs investigating. It
> is likely to be the case that this is not an entirely apples-to-apples
> comparison since the record cache holds records for a maximum of
> 'commit.time.ms', which by default is 30 seconds. So the record cache is
> adding quite a bit of latency, and we know that, however documenting the
> tradeoff and looking if there is any other bugs needs to be done.
