HAQM RDS for MariaDB now supports RDS Optimized Writes

HAQM Relational Database Service (HAQM RDS) for MariaDB now supports HAQM RDS Optimized Writes enabling up to 2x higher write throughput at no additional cost. This is especially useful for RDS for MariaDB customers with write-intensive database workloads, commonly found in applications such as digital payments, financial trading, and online gaming.

In RDS for MariaDB, you are protected from data loss due to unexpected events, such as a power failure, using a built-in feature called the “doublewrite buffer”. But this method of writing takes up to twice as long, consumes twice as much I/O bandwidth, and reduces the throughput and performance of your database. Starting today, HAQM RDS Optimized Writes provides you with up to 2x improvement in write transaction throughput on RDS for MariaDB by writing only once while protecting you from data loss and at no additional cost. Optimized Writes uses Torn Write Prevention, a feature of the AWS Nitro System, to reliably and durably write to table storage in one step.

HAQM RDS Optimized Writes is available as a default option from RDS for MariaDB version 10.6.10 and higher on db.r6i, db.r6g, db.r5b, db.x2iedn and db.x2idn database instances. Optimized Writes is available in all AWS regions where these instances are supported including AWS GovCloud (US-East, US-West) Regions.
