Hi All, We are pleased to announce the release of Apache Doris 1.1.1.
Apache Doris is an MPP-based interactive SQL data warehousing for reporting and analysis. The release is available at: https://doris.apache.org/download/ In this release, we add some important features and have a big performance improvement: 1. Support ODBC Sink in Vectorized Engine. This feature is enabled in non-vectorized engine but it is missed in vectorized engine in 1.1. So that we add back this feature in 1.1.1. 2. Simple Memtracker for Vectorized Engine. There is no memtracker in BE for vectorized engine in 1.1, so that the memory is out of control and cause OOM. In 1.1.1, a simple memtracker is added to BE and could control the memory and cancel the query when memory exceeded. 3. Cache decompressed data in page cache. Some data is compressed using bitshuffle and it costs a lot of time to decompress it during query. In 1.1.1, doris will decompress the data that encoded by bitshuffle to accelerate query and we find it could reduce 30% latency for some query in ssb-flat. Thanks to everyone who has contributed to this release, and more detail release note can also be found here: https://github.com/apache/doris/issues/11121 -- Best Regards, Yi Guo Lei SelectDB The Best Cloud Native Platform for Apache Doris Tel:134-3991-0228 Email:yiguo...@gmail.com
