In this patch set, written by Piotr Sarna and myself, we add Alternator - a new
Scylla feature adding compatibility with the API of Amazon DynamoDB(TM).
DynamoDB's API uses JSON-encoded requests and responses which are sent over
an HTTP or HTTPS transport. It is described in detail on Amazon's site:
https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/
Our goal is that any application written to use Amazon DynamoDB could
be run, unmodified, against Scylla with Alternator enabled. However, at this
stage the Alternator implementation is incomplete, and some of DynamoDB's
API features are not yet supported. The extent of Alternator's compatibility
with DynamoDB is described in the document docs/alternator/alternator.md
included in this patch set. The same document also describes Alternator's
design (and also points to a longer design document).
By default, Scylla continues to listen only to Cassandra API requests and not
DynamoDB API requests. To enable DynamoDB-API compatibility, you must set
the alternator-port configuration option (via command line or YAML) to the port on
which you wish to listen for DynamoDB API requests. For more information, see
docs/alternator/alternator.md. The document docs/alternator/getting-started.md
also contains some examples of how to get started with Alternator.
