Hi all, I think the iotdb is ready for release v1.3.3. Here is the draft of the release note, please check it.
## Features & Improvements - AINode: AINode is provided in the open source version. - Storage Engine: Added new data types String, Blob, Date, and Timestamp. - Storage Engine: Multi-level storage has added a rate-limiting mechanism. - Storage Engine: New merge target file splitting feature, with additional configuration file parameters, and improved memory control performance of the merge module. - Data Query: Filter performance optimization, enhancing the speed of aggregate queries and where condition queries. - Data Query: New client query requests load balancing optimization. - Data Query: New active metadata statistics query added. - Data Query: Optimized memory control strategy during the query planning phase. - Data Synchronization: The sender supports transferring files to a specified directory, and the receiver automatically loads them into IoTDB. - Data Synchronization: The receiver has a new automatic conversion mechanism for data type requests. - Data Synchronization: Enhanced observability on the receiver side, supporting ops/latency statistics for multiple internal interfaces, consolidated into a single pipeTransfer display. - Data Loading: DataNode actively listens and loads TsFiles, with additional observability metrics. - Stream Processing Module: New data subscription capability, supporting subscription to database data in the form of data points or tsfile files. - Stream Processing Module: Alter Pipe supports the ability to alter the source. - System Management: Optimized configuration files, with the original three configuration files merged into one, reducing user operational costs. - System Management: Optimized restart recovery performance, reducing startup time. - System Management: Internal addition of monitoring items such as device count, estimated remaining time for data synchronization, size of data to be synchronized, and synchronization speed. - Scripts and Tools: The import-tsfile script is expanded to support running the script on a different server from the IoTDB server. - Scripts and Tools: New metadata import and export scripts added. - Scripts and Tools: New support for Kubernetes Helm added. ... ## Bugs - Fixed the issue of NullPointerException (NPE) when merging chunks with modifications and empty pages in the sequential space. - Fixed the issue where the wrong parent file was used when reassigning the file position for skipped files during merge, leading to failure in creating hard links. - Fixed the issue where the newly added four data types had null values written, and the TsFile handling of the STRING type was incorrect, causing a BufferUnderflowException: null. - Fixed the issue in the high availability scenario where stopping the DataNode resulted in a PipeException: Failed to start consensus pipe. - Fixed the issue in Stream mode where the first batch of written data points might require a flush to be synchronized. - Fixed the compatibility issue with pipe plugin upgrades. - Fixed the issue where the `ORDER BY` clause became ineffective when used in combination with `LIMIT` in the last query. ...
