There's are two HAP SANA Dialects, which have been maintained by Andrew Clemons from SAP. I think you should ask them if they want to extend the current support according to your needs.

Hi Vlad, thanks for your input. Do you plan to support Sap Hana for maximum performance? Do you test with it? http://www.sap.com/developer/topics/sap-hana-express.html

All HFT systems that I know (Tora Trading Services, Flow Traders, Open HFT) use Chronicle, memory mapped files without using any RDBMS. More, the best HFT systems operate below 100 microseconds already, to stay competitive. Hibernate is a tool meant for OLTP transactions, not OLAP, not HFT. Hibernate is suitable for web and enterprise applications, where, usually, a response time of 1 or 10 milliseconds is definitely fast.

2018 the requirement for banks that join high speed trading is an accuracy of less than 100 microseconds away from utc.

This means hibernate needs to be much faster or allow other concepts..

You're welcome. We've been running some benchmarks, and there were some optimizations being done for multi-tenancy, using a thread-local pooled optimizer. But for the pooled optimizer, if you increase the increment size, it takes around 150 microseconds to call the database sequence which is really fast.
