Dear community friends, we are pleased to announce that Apache Doris will officially release version 1.2.5 on June 19, 2023 ! In version 1.2.5, the Doris team has fixed nearly 210 bugs or performance improvements since the 1.2.4 release. At the same time, version 1.2.5 is also an iterative version of 1.2.4, which has higher stability. Welcome to download and experience.

Official website download page: https://doris.apache.org/download/

Behavior Changed

• The BE startup script will check that the maximum number of file handles in the system must be greater than or equal to 65536, otherwise the startup will fail.

• The BE configuration item is set to true enable_quick_compactionby default . That is, the Quick Compaction function is enabled by default. This function is used to optimize the problem of small files in the case of large batch import.

• After the dynamic partition attribute of the table is modified, it will no longer take effect immediately, and it will take effect only after the next dynamic partition table task scheduling (the default scheduling time is 10 minutes, so it will take effect after 10 minutes at the latest).

Improvement

• Optimize the use of bthread and pthread to reduce the RPC blocking problem during the query process.

• The Profile page of the FE front-end page adds a button to download the Profile.

• Added FE configuration recover_with_skip_missing_versionfor queries to skip problematic data copies under certain failure conditions.

• The row-level permission feature supports Catalog appearance.

• Hive Catalog supports automatic refreshing of kerberos tickets on the BE side without manual refreshing.

• The JDBC Catalog supports tables under the MySQL/ClickHouse system library ( information_schema).

Bug Fixes

• Fixed the problem of incorrect query results caused by low-cardinality column optimization

• Fixed several authentication and compatibility issues accessing HDFS.

• Fixed several issues with floating point and decimal types.

• Fixed several issues with date/datetimev2 types.

• Fixed several query execution and planning issues.

• Fixed several issues with JDBC Catalog.

• Fixed several query-related issues with Hive Catalog, and Hive Metastore metadata synchronization issues.

• Fix incorrect show load profileresults .

• Fixed several memory related issues.

• Fixed several issues with CREATE TABLE AS SELECTthe function .

• Fix the problem that the JSONB type causes BE to crash on models that do not support avx2.

• Fixed several issues with dynamic partitions.

• Fixed several issues with TopN query optimization.

• Fixed several issues with the Unique Key Merge-on-Write table model.
