[Release Note 1.2.2](https://github.com/apache/doris/issues/16446) WIP ## Improvement - JDBC Catalog - Support connecting to Doris clusters through JDBC Catalog. - https://doris.apache.org/zh-CN/docs/dev/lakehouse/multi-catalog/jdbc#doris - Support to synchronize only the specified database through the `only_specified_database` attribute. - Support synchronizing table names in the form of lowercase through `lower_case_table_names` to solve the problem of case sensitivity of table names. - https://doris.apache.org/zh-CN/docs/dev/lakehouse/multi-catalog/jdbc - Optimize the read performance of JDBC Catalog. - Elasticsearch Catalog - Support Array type mapping. - Support whether to push down the `like` expression through the `like_push_down` attribute to control the CPU overhead of the ES cluster. - https://doris.apache.org/zh-CN/docs/dev/lakehouse/multi-catalog/es - Hive Catalog - Support Hive table default partition `__HIVE_DEFAULT_PARTITION__`. - Hive Metastore metadata automatic synchronization supports notification event in compressed format. - Dynamic partition supports specifying the `storage_medium` parameter to control the storage medium of the newly added partition. - https://doris.apache.org/zh-CN/docs/dev/advanced/partition/dynamic-partition - Optimize BE's threading model to avoid stability problems caused by frequent thread creation and destroy. ## Bug Fixes - Fixed issues with Merge-On-Write Unique Key tables. - Fixed compaction related issues. - Fixed some delete statement issues causing data errors. - Fixed several query execution errors. - Fixed the problem of using JDBC catalog to cause BE crash on some operating system. - Fixed Multi-Catalog issues. - Fixed memory statistics and optimization issues. - Fixed decimalV3 and date/datetimev2 related issues. - Fixed load transaction stability issues. - Fixed light-weight schema change issues. - Fixed the issue of using `datetime` type for batch partition creation. - Fixed the problem that a large number of failed broker loads would cause the FE memory usage to be too high. - Fixed the problem that stream load cannot be canceled after dropping the table. - Fixed querying `information_schema` timeout in some cases. - Fixed the problem of BE crash caused by concurrent data export using `select outfile`. - Fixed transactional insert operation memory leak. - Fixed several query/load profile issues, and supports direct download of profiles through FE web ui. - Fixed the problem that the BE tablet GC thread caused the IO util to be too high. - Fixed the problem that the commit offset is inaccurate in Kafka routine load. -- This is an automated message from the Apache Git Service.
