To the best of my knowledge, Meta has significantly reduced its investment in the Velox project. Apart from Meta, I'm not aware of any other major company that really uses Velox in a production environment. Frankly speaking, Velox may have already missed the window of opportunity for rapid development. If you're looking for a vectorized execution engine, you could consider ClickHouse (www.clickhouse.com) or StarRocks (www.starrocks.io). If your data analysis scenarios require more multi-table join operations, StarRocks is clearly a better choice.


This isnt really true, Meta if anything has doubled down on Velox.


Curious if you’re both right. Could it be because of the orgs involved? Which teams are using it? What products?


Presto is actively switching to use Velox as the backend ( https://github.com/prestodb/presto/tree/master/presto-native... ) . It is also being used extensively internally, again the paper describes these and their usages have grown , not reduced.


This thread clearly has folks from Clickhouse trying to talk down the project. Could you provide any data or evidence to support your claim?
