Migrating from Amazon QLDB to ScalarDL

Amazon announced that it will end the support for Amazon QLDB and introduced ScalarDL as an alternative solution in an AWS Japan blog post.

Like QLDB, ScalarDL (specifically ScalarDL Ledger) guarantees the integrity of data in databases and can detect data tampering*.

Difference between Amazon QLDB and ScalarDL.

As shown in the above diagram, although ScalarDL and QLDB have different interfaces, ScalarDL has similar capabilities to QLDB, so if you are looking for a solution to migrate from QLDB or QLDB alternatives, please check out the blog post.

* If you use ScalarDL Ledger with ScalarDL Auditor, ScalarDL guarantees that your system can detect arbitrary faults (i.e., Byzantine faults), including data tampering and malicious attacks.
