This part of the system allows you to execute a SQL query against the data in the SpaceClosed Where GigaSpaces data is stored. It is the logical cache that holds data objects in memory and might also hold them in layered in tiering. Data is hosted from multiple SoRs, consolidated as a unified data model..

Although the Space is a NoSQL data store, it exposes an SQL interface which is used for Data Queries.

Fill in the data query parameters, as shown below.

Data Query Parameters

  1. (Source drop-down list) – Select which GigaSpaces Space object the query should be executed against.

  2. (Load Query drop-down) - If there have been previous queries saved, they can be accessed from here.

  3. (Body of the query) – Enter a SQL-99 compliant query. What is displayed initially is sample syntax.

  2. Deploy – Allows a service to be created and deployed from a data query as an API endpoint, that will then appear in the list of Services in the Service menu.

    For XAP SkylineClosed A highly customizable developer platform that allows building scalable HA with high throughput and ultra-low latency Java applications running on Kubernetes clusters the Deploy option is not relevant.
