#AURORA AWS POSTGRESQL UPGRADE#

The AWS JDBC Driver for PostgreSQL is designed to coordinate with this behavior in order to provide minimal downtime in the event of a DB instance failure. It achieves this goal by electing an Aurora Replica to become the new primary DB instance, so that the DB cluster can provide maximum availability to a primary read-write DB instance. In an Amazon Aurora DB cluster, failover is a mechanism by which Aurora automatically repairs the DB cluster status when a primary DB instance becomes unavailable.

Use of the PostgreSQL driver in preview is subject to the terms and conditions contained in the AWS Service Terms, (particularly the Beta Service Participation Service Terms) This applies to any drivers not marked as 'Generally Available'. IMPORTANT Because this project is in preview, we encourage you to experiment with the PostgreSQL driver but DO NOT recommend adopting it for production use. Support for additional features of clustered databases, including features of Amazon RDS for PostgreSQL and on-premises PostgreSQL deployments, is planned. The AWS JDBC Driver for PostgreSQL supports fast failover for Amazon Aurora with PostgreSQL compatibility.

It is based on and is drop-in compatible with the PostgreSQL JDBC Driver, and is compatible with all PostgreSQL deployments. The Amazon Web Services (AWS) JDBC Driver for PostgreSQL allows an application to take advantage of the features of clustered PostgreSQL databases. Furthermore, the in-place feature and PostgreSQL version 12 support are available in all regions supported by Aurora PostgreSQL.Amazon Web Services (AWS) JDBC Driver for PostgreSQL More details on Amazon Aurora are available on the documentation landing page. Other available fully-managed Databases as a Service in the Cloud, such as Heroku Postgres, also support version 12.

Also, Google offers a managed relational database service for MySQL, PostgreSQL, and SQL Server called Cloud SQL, which supports versions 9.5, 9,6, 10, 11, 12, and 13. Microsoft has Azure Database for PostgreSQL and, according to their documentation, supports the community version of PostgreSQL 9.5, 9,6, 10, and 11, while the in preview Flexible Server supports 11 and 12. Aurora pricing is mainly based on instance size, and storage is billed according to actual usage.įurthermore, AWS is not the only cloud provider offering a managed relational database service compatible with PostgreSQL. RDS is priced based on the type and size of the instance and EBS volume. It also supports creating a highly available database cluster with synchronous replication across multiple availability zones.Īurora is generally more expensive than RDS for the same workloads. Furthermore, backups are continuous, incremental backups that do not affect database performance, up to 15 read replicas are supported, and failover is done fully automatically with no data loss. However, as Ismail Egilmez, business development manager at Thundra, explains in his blog:Īmazon Aurora improves on the performance of standard MySQL by 5x and improves on standard PostgreSQL by 2x, with the same hardware configuration.

#AURORA AWS POSTGRESQL UPGRADE#

Instead of a backup and restore to the new version, customers can upgrade with just a few clicks in the Amazon RDS Management Console or using the AWS SDK or CLI.ĪWS also offers Amazon Relational Database Service (RDS), which also supports the PostgreSQL database engine next to MySQL, SQL Server, MariaDB, and Oracle. In addition to the announcement of support of version 12 of PostgreSQL for Amazon Aurora, customers can also perform an in-place upgrade of your Amazon Aurora database cluster from PostgreSQL major version 11 to 12. The release with version 12 support also updates extensions including Address_standardizer, Address_standardizer_data_us, Amcheck, Citext, Hll, Hstore, Ip4r, Pg_repack, Pg_stat_statements, Pgaudit, Pglogical, Pgrouting, Plv8, Postgis, Postgis_tiger_geocoder, Postgis_topology. Furthermore, it also enables nondeterministic collations that support case-insensitive and accent-insensitive comparisons for ICU-provided collations, most common-value statistics for improved query plans, creation of generated columns that compute values with an expression, and many additional features. This new version includes better index management, improved partitioning capabilities, and executing JSON path queries per SQL/JSON specifications. AWS offers a PostgreSQL-compatible database as a fully-managed service with Amazon Aurora and now brings support for version 12 after previously providing support for minor versions 11.7, 10.12, and 9.6.17. PostgreSQL is an open-source object-relational database system that uses and extends the SQL language. AWS has recently announced that Amazon Aurora, a MySQL and PostgreSQL-compatible relational Database built for the Cloud, now supports major version 12 of PostgreSQL.
