DataStax delivers new API stack

DataStax announced a new API stack for modern data apps. Stargate, an open-source API framework for data first unveiled this summer, is now generally available in DataStax’s Astra cloud database and for free download on GitHub. The integration of Stargate into Astra enables developers to use any data store for modern data apps by adding support for new APIs, data types, and access methods. Developers no longer need to work with different databases and different APIs to power modern data apps. Developers can build data apps with:

  • Apache Cassandra: the open-source NoSQL database to manage data at global-scale.
  • K8ssandra: an open-source distribution that enables elastic scale for data on Kubernetes.
  • Stargate: an open-source API framework that enables developers to use their choice of schemaless JSON, GraphQL, and REST APIs.

And benefit from:

  • Choice of APIs — Developers can use their choice of the REST API, GraphQL API or schemaless Document API to access data.
  • No modeling — By using the Document API, developers can store JSON objects in Astra, without doing up front modeling. Developers can easily prototype without having to pre-define schema and queries.

Ontotext releases GraphDB 9.5

Ontotext released GraphDB 9.5, which includes data virtualization from tables to graphs and back. GraphDB makes it easy to turn any structured data into an uniform graph – one can access data in relational databases as a virtual graph as well as transform and reconcile tabular data into graphs with unambiguous semantics. GraphDB also makes it easy to consume data – along with the SPARQL protocol and the GraphQL interfaces, data can be accessed via JDBC to suit BI tools and a wide range of legacy systems.

The new release extends the JDBC driver for GraphDB functionality with a user-friendly interface to manage the SQL views. Part of GraphDB’s Workbench, the interface eliminates the need to access the database file system and performs validations of the input SPARQL query and its binding to SQL value types. All users with read access privileges can list the currently active SQL views, and those with write can create or modify them. The release brings also includes improved security and single sign-on support, performance optimizations, and bug fixes to SHACL validation and cluster support, upgrade to the latest version of RDF4J and upgraded connectors to Lucene, SOLR, and ElasticSearch.
