Venice is an open-source derived data platform developed by LinkedIn. It is used mainly for ML feature storage, which requires the ability to refresh data at very high throughput, and to look it up with low latency.
The lion share of the project is in Java, although it also leverages RocksDB and ZSTD via JNI. On the Java side, every bit of performance which can be squeezed is fair game.
After briefly presenting Venice, this talk then deep dives into some of the tricks we have employed in our relentless pursuit to lower read latency and to reach 1M operations per second per node.
