Looks good. Jialin Qiao > From: "Haonan Hou"<hao...@apache.org> > Date: Fri, Nov 15, 2024, 14:51 > Subject: Ready for release v1.3.3 > To: <dev@iotdb.apache.org> > 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. > ... > > Best regards, > Haonan Hou >
