| <%=vars.product_name%> provides a SQL-like querying language called OQL that allows you to access data stored in <%=vars.product_name%> regions. |
| |
| Since <%=vars.product_name%> regions are key-value stores where values can range from simple byte arrays to complex |
| nested objects, <%=vars.product_name%> 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. |
