TL;DR:
When bumping module, users will need to take action and set the
db_iopsvalue to be at least12000for below 14 + 8 = 22 DBsFor 14 postgres/mariadb
For 8 oracle
Background
We have cut the major
8.0.0release for RDS module and we are going to bump the modules across our platform.For all RDS DB engines except RDS for SQL Server, the baseline storage performance for gp3 volumes increases when the storage size reaches certain thresholds. This means that when user upgrade the module and switch to
gp3, they may need to adjust thedb_iopsvalue accordingly to ensure optimal performance, especially for RDS instances with large volumes.gp3Storage TypeWhen bumping module, users will need to take action and set the
db_iopsvalue to be at least12000for :Db2,MariaDB,MySQL,PostgreSQLwith larger than 399allocated_storageandgp2storage_type(We have 14 DB as of Oct 24 20:00 in this case.)Oraclewith larger than 199allocated_storageandgp2storage_type(We have 8 DB as of Oct 24 20:00 in this case.)The complete output are in below comment.
