Dear community, Here’s the latest update on IoTDB development progress at Timecho this week:
- Pipe Core: (1)Fixed an issue in mixed-mode Pipe where file and operation captures might not follow the expected commit sequence, preventing potential data loss in edge cases. (2) Optimized memory tracking for Binary data types to avoid Out-Of-Memory (OOM) issues. - Data Subscription: Resolved long execution times when exporting subscribed data. - Data Sync:iotdb-sink now supports the skip-if parameter to bypass data that fails authentication checks. - SQL & Query Enhancements: (1) Completed implementation of ASOF LEFT JOIN. (2) Benchmarked and optimized performance for Last queries. (3) Implemented sort elimination for multi-table JOIN operations. (4) Added SQL support to cancel data subscriptions. (5) Disallowed key changes after IoTDB startup for security consistency. - MQTT Enhancements: (1) Added interface for passing the topic to plugins. (2) MQTT external source now supports topic as a statement parameter. - Performance & Security Fixes: Fixed an issue where permission cache was not effective, leading to degraded write performance for non-root users. - Active Load: Fixed an issue where the db parameter could not be passed in during async load via SQL. - Resolved a CVE-related security issue in the Procedure module. - Enhanced deserialization safety in ConfigNode. As always, your feedback and contributions are welcome. Thank you for your continued support! Best regards, Pengcheng The Timecho Team
