Jul 1, 2025July 2025 monthly summary for crossoverJie/starrocks. Focused on delivering business value through improved query capabilities in the data plane: implemented pipe name filtering in SHOW PIPES with LIKE and EQUAL conditions, enabling WHERE clauses to filter by pipe name; fixed a bug to support equal or like name filtering (commit 034d1f82b4e54c3f8988eea055e7593a8afdb402). Impact: improves query precision, reduces post-processing, and enhances pipe visibility for operators. Technologies/skills demonstrated: SQL pattern matching, query engine enhancement, version control discipline, and issue tracking. Repository: crossoverJie/starrocks.

Mar 1, 2025March 2025: Focused on stabilizing and improving reliability of materialized views in crossoverJie/starrocks. Delivered a targeted bug fix to the materialized view path, addressing an error in originalViewDefineSql by correctly extracting the original view definition using both the start and stop indices. The fix aligns with issue #56172 and is tracked by commit 53737b1b8e2f9753cd7e6ee885ecc94fa98597c9. This work reduces MV creation failures and improves downstream data pipelines. No new user-facing features released this month; the emphasis was on robustness, test coverage, and maintainability of MV-related code.

Feb 1, 2025February 2025 monthly summary for crossoverJie/starrocks focusing on business value and technical achievements. This period prioritized correcting time-handling in Hive Parquet integration to improve data reliability. The main deliverable was a high-impact bug fix addressing daylight saving time (DST) handling, introducing dynamic timezone offset calculation for timestamps used in Hive catalog Parquet tables. No new features were released this month; however, the fix eliminates DST-related timestamp inaccuracies, enhancing data correctness in downstream analytics and production queries. The work aligns with issue #55899 and involved careful review of time conversion code paths, particularly around Int96ToDateTimeConverter usage.
