This adds a BLOOM_FILTER_ERROR_RATE option that takes a value between 0 and 1 (exclusive) that can override the default target false positive probability (fpp) value of 0.75 for selecting the filter size. It does not affect whether filters are disabled at runtime. Adds estimated FPP and bloom size to the routing table so we have some observability. Here is an example: tpch_kudu> select count(*) from customer join nation on n_nationkey = c_nationkey; ID Src. Node Tgt. Node(s) Target type Partition filter Pending (Expected) First arrived Completed Enabled Bloom Size Est fpp ----------------------------------------------------------------------------------------------------------------------------------------- 1 2 0 LOCAL false 0 (3) N/A N/A true MIN_MAX 0 2 0 LOCAL false 0 (3) N/A N/A true 1.00 MB 1.04e-37 Testing: Added a test that shows the query option affecting filter size. Ran core tests.
