QO 2023-01-23
The query
{$match: {"chi2_int_10000000_1000" :
{ "$gt" : 4017000, "$lt" : 4018000}}}
over ce_data_100000 collection from CE accuracy tests fails with invalid cardinality estimate.
To reproduce:
0) Run data generator
1) Load CE accuracy data executing the commands from jstests/query_golden/load_data.js
2) Run the query
load("jstests/libs/ce_stats_utils.js"); load("jstests/libs/optimizer_utils.js"); load("jstests/query_golden/libs/run_queries_ce.js"); let collMeta = dbMetadata[3]; // check the collection is ce_data_100000 let collName = collMeta.collectionName; let coll = testDB[collName]; let testCase = {_id: 0, pipeline: [{$match: {"chi2_int_10000000_1000" : { "$gt" : 4017000, "$lt" : 4018000} }}], "dtype": "int", "qtype" : "$gt"}; let strategy = "histogram"; forceCE(strategy); runAggregationWithCE(coll, testCase, strategy);
