Summary: Sql. Adjust cost estimation for index scan Key: IGNITE-21721 URL: https://issues.apache.org/jira/browse/IGNITE-21721 Project: Ignite Issue Type: Improvement Components: sql Reporter: Konstantin Orlov Scan over an index if significantly slower than scan over a table. In some cases (for example, TPC-H q4 on scaleFactor=0.1) it's faster to read an entire table and do sorting in memory rather than scan the index. Let's adjust cost function to reflect the real complexity of index scan. -- This message was sent by Atlassian Jira (v8.20.10#820010)
