+# QUARKUS-2148 - Add support for sending query params as using a Map in Reactive Rest Client
+
+JIRA link: https://issues.redhat.com/browse/QUARKUS-2148
+
+PR: https://github.com/quarkusio/quarkus/pull/24783
+
+Upstream issue: https://github.com/quarkusio/quarkus/issues/24764
+
+
+The REST Client Reactive now supports passing query parameters as map. This can be very useful if query parameters are not known
+in advance. For primitive data types and Java classes that are not a `Map` implementation, `@RestQuery` annotation still resolves 
+query key from `@RestQuery#value()`, or from a formal parameter name. Each `Map.Entry` represent a key and value of a query parameter.
+Query parameters whose values are arrays can be passed as a `MultivaluedMap`;
+
+## Scope of the testing
+
+Tests should verify:
+- User is able to pass query parameters as map.
+- Primitive and complex data types and arrays can be sent.
+- Multiple query parameter maps can be specified.
+- Query parameter map works in a native mode.
+
+### Impact on testsuites and testing automation:
+
+New scenario is going to be added to the `http/rest-client-reactive` module of Quarkus Test suite. One test method is
+going to be needed as well as respective endpoint that handles dynamic number of query parameters. All verifications can be done
+with one call as `@RestQuery` is repeatable.
+
+### Impact on resources:
+
+- No additional requirements for resources in lab
+- Required additional time for the test execution should be below 4 seconds
+- No measurable additional requirements for a Native image scenario
+
+## Getting familiar with the feature
+
+Following actions were taken to ensure familiarity:
+- Ensure documentation provides clear explanation on configuration options
+- Ensure good user experience and simplicity of use
+
+## Advanced topics for test development
+
+- No advanced topics found
