----------------------------------
Summary: LikePattern matching time grows exponentially with the
number of '%' wildcards
Key: CALCITE-7906
URL: https://issues.apache.org/jira/browse/CALCITE-7906
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Ruben Q L
Assignee: Ruben Q L
Fix For: 1.43.0
LikePattern.likeToRegex turns each % into .* and matches with java.util.regex.
A pattern with many wildcards makes the regex engine backtrack heavily when the
name doesn't match.
