The Apache IoTDB team is pleased to announce the release of Apache IoTDB 1.3.1.
Apache IoTDB (Database for Internet of Things) is an IoT native database with high performance for data management and analysis, deployable on the edge and the cloud. Apache IoTDB 1.3.1 is the latest version of the v1 series. Feel free to upgrade from earlier version. ## Features & Improvements - Add cluster script for one-click start-stop (start-all/stop-all.sh & start-all/stop-all.bat) - Add script for one-click instance information collection (collect-info.sh & collect-info.bat) - Add new statistical aggregators include stddev and variance - Add repair tsfile data command - Support setting timeout threshold for Fill clause. When time beyond the threshold, do not fill value. - Simplify the time range specification for data synchronization, directly set start and end times - Improved system observability (adding dispersion monitoring of cluster nodes, observability of distributed task scheduling framework) - Optimized default log output strategy - Enhance memory control for Load TsFile, covering the entire process - Rest API (Version 2) adds column type return. - Improve the process of query execution - Session automatically fetch all available DataNodes ... ## Bugs - Fix issue with abnormal behavior when time precision is not in milliseconds during grouping by month. - Fix issue with abnormal behavior when duration contains multiple units during grouping by month. - Fix bug where limit and offset cannot be pushed down when there is an order by clause. - Fix abnormal behavior in combination scenario of grouping by month + align by device + limit. - Fix deserialization errors during IoT protocol synchronization. - Fix concurrent exceptions in deleting timeseries. - Fix issue where group by level in view sequences does not execute correctly. - Fix potential issue of metadata creation failure when increasing election timeout.
