Among these, the most noteworthy features are the MySQL protocol and ANSI SQL compatibility, along with the extended SQL syntax capabilities. + +Firstly, MySQL protocol compatibility allows OpenMLDB users to access OpenMLDB clusters using any MySQL client, not limited to GUI applications like NaviCat or Sequal Ace but also Java JDBC MySQL Driver, Python SQLAlchemy, Go MySQL Driver, and various programming language SDKs. For more information, you can refer to "[**Ultra High-Performance Database OpenM(ysq)LDB: Seamless Compatibility with MySQL Protocol and Multi-Language MySQL Client**](20240322_Openmysqldb.md)". + +Secondly, the new version significantly expands SQL capabilities, especially implementing OpenMLDB’s unique request mode and stored procedure execution within standard SQL syntax. Compared to traditional SQL databases, OpenMLDB covers the entire machine learning process, including offline and online modes. In online mode, users can input sample data, and get feature results through SQL feature extraction. On the contrary, in the past, we needed to deploy SQL as a stored procedure through the `Deploy` command and then perform online feature computation through SDKs or HTTP interfaces. The new version adds `SELECT CONFIG` and `CALL` statements, allowing users to directly specify request mode and sample data in SQL to compute feature results, as shown below: + +``` +-- Execute online request mode query for action (10, "foo", timestamp(4000)) +SELECT id, count(val) over (partition by id order by ts rows between 10 preceding and current row) +FROM t1 +CONFIG (execute_mode = 'online', values = (10, "foo", timestamp(4000))) +``` +You can also use the ANSI SQL `CALL` statement to invoke stored procedures with sample rows as parameters, as shown below: + +``` +-- Execute online request mode query for action (10, "foo", timestamp(4000)) +DEPLOY window_features SELECT id, count(val) over (partition by id order by ts rows between 10 preceding and current row) +FROM t1; + +CALL window_features(10, "foo", timestamp(4000)) +``` +For detailed release notes, please refer to: [https://github.com/4paradigm/OpenMLDB/releases/tag/v0.9.0](https://github.com/4paradigm/OpenMLDB/releases/tag/v0.9.0) + +Please feel free to download and explore the latest release.
