As the main maintenance team of Apache Doris community, Baidu Palo team also maintains 3-bit iterative Version (tags) (What is 3-bit version) based on the official release version of Apache Doris, including fast Bug repair and new function update.

These 3-bit iterations have been tested in Baidu internally and have been made online, which are recommendable.

Open-source users can download our 3-bit iterative version for free. Please refer to the official Apache Doris website at the end of the document for the installation and deployment method.

Download open-source version

• In some cases, the user may not be able to get the binary file of Doris smoothly through source code compilation. Here we provide the pre-compiled binary download of the corresponding 3-bit version.
• We strongly recommend users to generate binary files through source code compilation.
• The pre-compiled binary files provided here only run on CentOS 7.3, Intel (R) Xeon (R) Gold 6148 CPU @ 2.40GHz for execution. In other systems or CPU models, the files may not run because of different glibc versions or different instruction sets supported by CPU.
• The FE part of the pre-compiled binary file is compiled with Oracle JDK 1.8, so please make sure that Oracle JDK 1.8 is still used at runtime.

• Pre-compile includes the following components

  1. Frontend
  2. Backend
  3. Broker
  4. Frontend plugins jars
  5. Spark-Doris-Connector jars

Change Log

• 0.13.15

  1. New functions:

     • A new Join Reorder algorithm is added, which has obvious optimization effect in TPCDS 17, 25, 37, 54, 82, 84, 85 and other complex Join queries. Join Reorder.
     • It supports the calculation of all constant expressions through BE to solve the problem that FE is not able to calculate constant expressions. Constant expression folding.
     • It supports Export the data to ODBC external table.
     • TopN aggregate function is added.

  2. Optimization:

     • It can optimize the data reading logic of storage engine to improve the query performance, including version merging, predicate push down and so on.
     • Through parameter fuzzy_ Parse , it can optimize part loading speed of scenario JSON Data Loading.

  3. Serious bug fix:

     • Fix the problem that loading JSON format data may cause BE memory leak.
     • Fix the problem that BE execution of compact logic may cause disk space not to be released.
     • Fix the problem of BE downtime caused by Delete condition containing predicateIS NULL/IS NOT NULL.
     • Fix the problem that Routine Load consumes Kafka data and may lose data in some cases.
     • Fix some query problems.

Instructions

All 3-bit iterative version of the source code can be seen here Baidu-Doris

Currently, the official release version of Apache Doris is:

• 0.9.0
• 0.10.0
• 0.11.0
• 0.12.0
• 0.13.0

This repository mainly releases 3-bit iterative version based on 2-bit official version. For example:

• DORIS-0.9.22-release
• DORIS-0.10.23-release
• DORIS-0.11.44-release
• DORIS-0.12.21-release
• DORIS-0.13.11-release

All 3-bit versions can be safely upgraded from the corresponding official 2-bit version. The 3-bit version itself is compatible and can be upgraded safely. Here are the examples:

• Official version 0.12.0-rc02 can be upgraded to DORIS-0.12.21-release
• DORIS-0.11.10-release can be upgraded to DORIS-0.11.44-release
• DORIS-0.11.44-release can be upgraded to DORIS-0.12.21-release

It is recommended to upgrade to the latest 3-bit version before upgrading to the 2-bit version. Here are the examples:

1. Current version is DORIS-0.11.10-release, if you want to upgrade it to version 0.12 .
2. First upgrade to DORIS-0.11.44-release, that is, the latest 3-bit version of 0.11
3. Then upgrade to DORIS-0.12.21-release, that is, the latest 3-bit version of 0.12.

The 3-bit iterative version can also be safely upgraded with the official 2-bit version. For example, the following upgrade sequence is safe:

Docker compile environment image download

We recommend that open-source users compile Doris by themselves through the source code.

But there are some reasons that cause slow download of imagedocker.io/apachedoris/doris-dev:build-env-1.2 through the method of docker pull. We can download the image locally through the following links, and then load the image through docker load command:

Download docker.io/apachedoris/doris-dev:build-env-1.2

docker load --input apachedoris-build-env-1.2

After this, we can view the image through docker images.
