As I discussed in my re:Invent keynote earlier this month, I am now happy to announce the immediate availability of Amazon RDS Cross Region Read Replicas , which is another important enhancement for our customers using or planning to use multiple AWS Regions to deploy their applications. Cross Region Read Replicas are available for MySQL 5.6

We introduce a caching mechanism in the API gateway layer, allowing us to offload processing from singleton leader elected controllers without giving up strict data consistency and guarantees clients observe. For example, it is OK to send writes through one instance, and do reads from another one with full data read consistency guarantees.

For example, on a 128GB memory host, this can allow up to 38.4GB of dirty pages. Make sure the drives are mounted with noatime and also if the drives are behind a RAID controller with appropriate battery-backed cache. The background ratio won’t kick in until 12.8GB. By default, it uses 50% of the memory + 1 GB.

Cons of logical backups As it reads all data, it can be slow and will require disk reads too for databases that are larger than the RAM available for the WT cache—the WT cache pressure increases, which slows down the performance. Especially if going into or out of storage types that may throttle bandwidth/network traffic.

In the first example section I added a couple of paragraphs on “choreography over orchestration”. I was a little restricted in my thinking the first time around and I’ve come to see FaaS as something not quite stateless, since caching state in a Lambda instance that might stick around for 5 hours is a perfectly reasonable idea.

Elasticsearch recommends each shard to be under 65GB (AWS recommends them to be under 50GB), so we could create time based indices where each index holds somewhere between 16–20GB of data, giving some buffer for data growth. For every asset indexing request, we look at the cache to determine the corresponding time bucket index for the asset.
