Amazon Relational Database Service (Amazon RDS) for MySQL now supports Amazon RDS Optimized Writes. With Optimized Writes you can improve write throughout by up to 2x at no additional cost. This is especially useful for RDS for MySQL customers with write-intensive database workloads, commonly found in applications such as digital payments, financial trading, and online gaming.
In MySQL, 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, Amazon RDS Optimized Writes provide you with up to 2x improvement in write transaction throughput on RDS for MySQL by writing only once while protecting you from data loss and at no additional cost. Optimized Writes uses the Amazon Nitro System, to reliably and durably write to table storage in one step.
Amazon RDS Optimized Writes is available as a default option from RDS for MySQL version 8.0.30 and above and on db.r6g database instances. Optimized Writes is generally available in the Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.
