------------------------------
Summary: Move MongoDB LIKE-to-regex conversion into runtime.Like
for consistency
Key: CALCITE-7693
URL: https://issues.apache.org/jira/browse/CALCITE-7693
Project: Calcite
Issue Type: Improvement
Components: mongodb-adapter
Affects Versions: 1.42.0
Reporter: Yu Xu
Assignee: Yu Xu
Fix For: 1.43.0
Follow-up to the initial MongoDB LIKE
support(https://issues.apache.org/jira/browse/CALCITE-7673). In review it was
noted that the SQL-LIKE-to-regex conversion logic embedded in MongoFilter
duplicated a pattern Calcite already establishes in
org.apache.calcite.runtime.Like (see Like.sqlToRegexLike). Keeping the
conversion inside the adapter meant a second, independently-maintained
escape/wildcard translator with its own special-character table and error
handling.
