Subject Re: Supported data types for predicate pushdown
Date Mon, 03 Oct 2016 21:02:03 GMT
No support for binary and complex types yet. Date and timestamp should work.
The way it works is for all supported data types min/max value is checked first. 
If it returns true and if the bloom filter exists for that column type then bloom filter is
If min/max itself returns false we don’t check bloom filter.
