   It won't block any read/write requests but it can block Disruptor RingBuffer requests that are being consumed. I am thinking of having a cron which can run every 10 min and whatever slow records are present in in-memory ring buffer, those can be put in table in one go. The downside is we might miss some records, the upside is we might not have to worry about slow system blocking the new system table inserts, at least after 10 min we expect system to be in better state. WDYT @Apache9 ?
