Platform›SQL Querying
SQL Querying
Use SQL to query data in maps, Kafka topics, or a variety of file systems. Results can be sent directly to the client or inserted into maps or Kafka topics.
Use an Industry Standard for Querying Data
Hazelcast supports SQL querying to allow anyone familiar with the industry-standard language to interact with in-memory data. Leveraging the sophisticated query engine built into Hazelcast, the SQL support adds a well-known interface to run queries and offers:
- The ability to query large amounts of data in an industry-standard way, with the same query specificity of the existing Hazelcast Predicate-based design
- The option to make use of a new, high-performance concurrent off-heap B+ tree indexes
- More advanced query optimization
