If you check the official page for DynamoDB you see this under how it works "DynamoDB offers built-in security, continuous backups, automated multi-region replication, in-memory caching, and data export tools."
In the command line options you have the option -inMemory – DynamoDB runs in memory instead of using a database file (See https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.UsageNotes.html"
You can also check "In-Memory Acceleration with DynamoDB Accelerator (DAX)"
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DAX.html
Thanks, I thought DAX is a separate service, not an option for DynamoDB. I looked here: https://aws.amazon.com/nosql/in-memory/ and they don’t mention DynamoDB/DAX at all 🙁
