Depends on the data size. It's definitely not worth it for gigabytes, and for petabytes, there's not much else. Terabytes are in the middle.

- maxxxxx 8y agoAren't there petabyte SQL databases in existence? You can't use Hadoop for transactional data so I suppose that data still goes into SQL.
- Triffids 8y agoIt depends. There are Cloudera kudu engine, it quite easy can handle millions atomic inserts per second. But it can't support true acid transaction. On other hand SQL also can't use true ACID in high load system. Serialazible transactions replaced by Read committed transactions, "banking day", queues + background process, etc
