Vhayu's Velocity (too many Velocity's out there!) now has data compression performed by FPGAs. This looks like pretty impressive stuff, and sets the bar a bit higher for KDB.
With on-the-fly data compression, you can have more tick and trade data available for backtesting, and since the compression is done in hardware, this should reduce the latency compared with software-based on-the-fly compression.
Even though this is pretty good news, I wonder if Compliance Departments might have an issue with storing zipped data, as it is not readily available for inspection and analysis by non-Vhayu applications. But that is a trade-off that you will need to make. I am sure Ross Dubin can further enlighten us on this...
I would rename the product from Velocity to ZIP-ON-A-CHIP.
