VMware GemFire provides a SQL-like querying language called OQL that allows you to access data stored in VMware GemFire regions.
Since VMware GemFire regions are key-value stores where values can range from simple byte arrays to complex nested objects, VMware GemFire uses a query syntax based on OQL (Object Query Language) to query region data. OQL is very similar to SQL, but OQL allows you to query complex objects, object attributes, and methods.
This topic answers some frequently asked questions on querying functionality. It provides examples to help you get started with VMware GemFire querying.
This section provides a high-level introduction to VMware GemFire querying such as building a query string and describes query language features.
This section includes advanced querying topics such as using query indexes, using query bind parameters, querying partitioned regions and query debugging.
The VMware GemFire query engine supports indexing. An index can provide significant performance gains for query execution.
