Aurora MySQL database engine updates 2019-11-25 (version 2.07.0) (Deprecated) (original) (raw)

Version: 2.07.0

Aurora MySQL 2.07.0 is generally available. Aurora MySQL 2.x versions are compatible with MySQL 5.7 and Aurora MySQL 1.x versions are compatible with MySQL 5.6.

Currently supported Aurora MySQL releases are 1.19.5, 1.19.6, 1.22.*, 1.23.*, 2.04.*, 2.07.*, 2.08.*, 2.09.*, 2.10.*, 3.01.* and 3.02.*.

You can restore a snapshot from a currently supported Aurora MySQL release into Aurora MySQL 2.07.0. You also have the option to upgrade existing Aurora MySQL 2.* database clusters to Aurora MySQL 2.07.0. You cannot upgrade an existing Aurora MySQL 1.* cluster directly to 2.07.0; however, you can restore its snapshot to Aurora MySQL 2.07.0.

To create a cluster with an older version of Aurora MySQL, please specify the engine version through the AWS Management Console, the AWS CLI, or the RDS API.

Note

This version is currently not available in the following AWS Regions: AWS GovCloud (US-East) [us-gov-east-1], AWS GovCloud (US-West) [us-gov-west-1], China (Ningxia) [cn-northwest-1], Asia Pacific (Hong Kong) [ap-east-1], Middle East (Bahrain) [me-south-1], and South America (São Paulo) [sa-east-1]. There will be a separate announcement once it is made available.

If you have any questions or concerns, AWS Support is available on the community forums and throughAWS Support. For more information, see Maintaining an Amazon Aurora DB cluster in the Amazon Aurora User Guide.

Improvements

New features:

• Global Databases now allow adding secondary read-only replica regions for database clusters deployed in these AWS Regions: regions: US East (N. Virginia) [us-east-1], US East (Ohio) [us-east-2], US West (N. California) [us-west-1], US West (Oregon) [us-west-2], Europe (Ireland) [eu-west-1], Europe (London) [eu-west-2], Europe (Paris) [eu-west-3], Asia Pacific (Tokyo) [ap-northeast-1], Asia Pacific (Seoul) [ap-northeast-2], Asia Pacific (Singapore) [ap-southeast-1], Asia Pacific (Sydney) [ap-southeast-2], Canada (Central) [ca-central-1], Europe (Frankfurt) [eu-central-1], and Asia Pacific (Mumbai) [ap-south-1].
• Amazon Aurora machine learning is a highly optimized integration between the Aurora MySQL database and AWS machine learning (ML) services. Aurora machine learning allows developers to add a variety of ML-based predictions to their database applications by invoking ML models using the familiar SQL programming language they already use for database development, without having to build custom integrations or learn separate tools. For more information, seeUsing machine learning (ML) capabilities with Amazon Aurora.
• Added support for the ANSI READ COMMITTED isolation level on the read replicas. This isolation level enables long-running queries on the read replica to execute without impacting the high throughput of writes on the writer node. For more information, seeAurora MySQL isolation levels.

Critical fixes:

• CVE-2019-2922
• CVE-2019-2923
• CVE-2019-2924
• CVE-2019-2910

High-priority fixes:

• Fixed an issue in the DDL recovery that resulted in prolonged database downtime. Clusters that become unavailable after executing multi-table drop statement, for example DROP TABLE t1, t2, t3, should be updated to this version.
• Fixed an issue in the DDL recovery that resulted in prolonged database downtime. Clusters that become unavailable after executingINPLACE ALTER TABLE DDL statements should be updated to this version.

General stability fixes:

• Fixed an issue that generated inconsistent data in the information_schema.replica_host_status table.

Comparison with Aurora MySQL version 1

The following Amazon Aurora MySQL features are supported in Aurora MySQL Version 1 (compatible with MySQL 5.6), but these features are currently not supported in Aurora MySQL Version 2 (compatible with MySQL 5.7).

• Asynchronous key prefetch (AKP). For more information, see Optimizing Aurora indexed join queries with asynchronous key prefetch in the Amazon Aurora User Guide.
• Scan batching. For more information, see Aurora MySQL database engine updates 2017-12-11 (version 1.16) (Deprecated).
• Migrating data from MySQL using an Amazon S3 bucket. For more information, see Migrating data from MySQL by using an Amazon S3 bucket in the Amazon Aurora User Guide.

MySQL 5.7 compatibility

Aurora MySQL 2.07.0 is wire-compatible with MySQL 5.7 and includes features such as JSON support, spatial indexes, and generated columns. Aurora MySQL uses a native implementation of spatial indexing using z-order curves to deliver >20x better write performance and >10x better read performance than MySQL 5.7 for spatial datasets.

Aurora MySQL 2.07.0 does not currently support the following MySQL 5.7 features:

• Group replication plugin
• Increased page size
• InnoDB buffer pool loading at startup
• InnoDB full-text parser plugin
• Multisource replication
• Online buffer pool resizing
• Password validation plugin
• Query rewrite plugins
• Replication filtering
• The CREATE TABLESPACE SQL statement
