AlterSystemPropertiesRequest (Kinetica Java API 7.2.3.1 API)

java.lang.Object
- com.gpudb.protocol.AlterSystemPropertiesRequest

All Implemented Interfaces:

org.apache.avro.generic.GenericContainer, org.apache.avro.generic.IndexedRecord
```
public class AlterSystemPropertiesRequest
extends Object
implements org.apache.avro.generic.IndexedRecord
```
A set of parameters for GPUdb.alterSystemProperties.
The GPUdb.alterSystemProperties endpoint is primarily used to simplify the testing of the system and is not expected to be used during normal execution. Commands are given through the propertyUpdatesMap whose keys are commands and values are strings representing integer values (for example '8000') or boolean values ('true' or 'false').
