Q: What are I/Os in Amazon Aurora and how are they calculated?

I/Os are input/output operations performed by the Aurora database engine against its SSD-based virtualized storage layer. Every database page read operation counts as one I/O. The Aurora database engine issues reads against the storage layer in order to fetch database pages not present in memory in the cache. If your query traffic can be totally served from memory or the cache, you will not be charged for retrieving any data pages from memory. If your query traffic cannot be served entirely from memory, you will be charged for any data pages that need to be retrieved from storage. Each database page is 16KB in Aurora MySQL and 8KB in Aurora PostgreSQL.

Aurora was designed to eliminate unnecessary I/O operations in order to reduce costs and to ensure resources are available for serving read/write traffic. Write I/Os are only consumed when persisting redo log records in Aurora MySQL or write ahead log records in Aurora PostgreSQL to the storage layer for the purpose of making writes durable. Write I/Os are counted in 4KB units. For example, a log record that is 1024 bytes will count as one write I/O operation. However, if the log record is larger than 4KB, more than one write I/O operation will be needed to persist it. Concurrent write operations whose log records are less than 4KB may be batched together by the Aurora database engine in order to optimize I/O consumption, if they are persisted on the same storage protection groups. Unlike traditional database engines, Aurora never flushes dirty data pages to storage.

Sure, the last one is 3d only in the Desktop OS, but it is testing the waters for a return of 3D. With both the usage of the frosted glass aesthetic (both Microsoft and Apple), skeuomorphic icons (Mac OS Big Sur update) people have generally reacted positively to the change.

You can see how many I/O requests your Aurora instance is consuming by going to the AWS Console. To find your I/O consumption, go to the RDS section of the console, look at your list of instances, select your Aurora instances, then look for the “Billed read operations” and “Billed write operations” metrics in the monitoring section.
