Unlock cassandra data for application developers using graphQL
0 likes73 views
This document discusses how Stargate provides a data gateway for unlocking Cassandra data for application developers through REST and GraphQL APIs. It introduces Stargate as an open source API framework that adds plugin support for new APIs, data types, and access methods to make it easy to use Cassandra for any application workload. It then covers the REST and GraphQL APIs provided by Stargate, how Stargate supports document and schemaless data through a document API, and how GraphQL queries can be mapped to CQL through both schema-first and CQL-first approaches.

- 26. Cassandra as Document Store • Cassandra already handles JSON and structures ● INSERT JSON, SELECT JSON ● Set<>, List<>,Map<>, and User Defined type (UDT) even nested ● BUT everything is strongly coupled with a VALIDATION • You want to insert and retrieve any JSON documents efficiently ● Allow “schemaless” ● Write to a single document is a single batch of statements ● Read from a single document is a single SELECT statement. ● Limit Tombstones with range deletes
