Database / ScyllaDB Interview questions
What is ScyllaDB Alternator?
Alternator is ScyllaDB's implementation of the DynamoDB HTTP API, letting applications written against AWS DynamoDB's SDKs point at a ScyllaDB cluster instead, with no application code changes beyond the endpoint URL.
aws dynamodb list-tables --endpoint-url http://scylla-node:8000
It supports DynamoDB's core operations, including GetItem, PutItem, Query, Scan, and Global/Local Secondary Indexes, translating them internally onto ScyllaDB's storage engine. Alternator exists mainly to give teams an exit path from DynamoDB's proprietary pricing and vendor lock-in, letting them run the same workload on self-managed or ScyllaDB Cloud infrastructure, on-premises or across multiple clouds, without a rewrite.
