Hello AWS experts,
I understand that DynamoDB (and more specifically to my question, DAX) follows an "eventually consistent" data consistency model, and this means there is an expected delay between when some data is written and when a query of that same data will return the most recent information.
I've been reviewing the DAX and DynamoDB consistency models documentation (https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DAX.consistency.html) and am trying to understand the expected time for data to reach consistency across all nodes in a DAX cluster. Specifically, I'm looking for an "order of magnitude" estimate. Is the expected time to consistency in the ballpark of 10ms, 100ms, 1000ms, or several seconds? This is specifically related to the consistency of data which has been inserted/updated using the DAX cluster (no write-around or other ways of circumventing the DAX cache).
Any insights or references to further documentation would be greatly appreciated. Thank you!
