Scylla Alternator: The Open Source DynamoDB-compatible API

Alternator

About Scylla’s Alternator Project Alternator is an open source project that gives Scylla compatibility with Amazon DynamoDB™. Our goal is that any application written for Amazon DynamoDB could be run, unmodified, against Scylla with Alternator enabled. Originally, Scylla began as a re-implementation of Apache Cassandra, and it has since proven to be a solid database engine with key performance and TCO benefits over Cassandra.

Global or Local Secondary Indexes in Scylla? The Choice Is Now Yours

Local Indexes Graphic

Indexing is a useful tool that provides more types of queries on your tables. In principle, columns we wish to be queryable should be declared when the table is created, as part of a table’s primary key. Secondary Indexing is a neat way of making other columns queryable, but it comes with a cost of additional storage space and processing power to maintain the secondary index data coherent with the primary index information.

Racing the Red Queen

“Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!” — The Red Queen to Alice, Alice Through the Looking Glass In the world of Big Data, if you are not constantly evolving you are already falling behind.
