Basic queries

Overview​

This page describes basic queries and how to create a new query policy.

Basic queries​

Basic queries are read-only queries that return records to the client. A client application makes an API request to start a read-only query. This request in turn initiates parallel requests to each node in the cluster. The result returns the current version of each record to the client.

Query policies​

note

The concept of short and long queries was introduced in Database 6.0. See Differences between short and long queries for more information.

Query policies can be passed on a per-request basis. Policy values can be set to create a filter expression, to determine whether bin data is included with the response, identify a short versus long query, and more.
