All Implemented Interfaces:

org.apache.avro.generic.GenericContainer, org.apache.avro.generic.IndexedRecord

public class CreateJobRequest
extends Object
implements org.apache.avro.generic.IndexedRecord

A set of parameters for GPUdb.createJob.

Create a job which will run asynchronously. The response returns a job ID, which can be used to query the status and result of the job. The status and the result of the job upon completion can be requested by GPUdb.getJob.

Constructor Detail

CreateJobRequest

public CreateJobRequest()

Constructs a CreateJobRequest object with default parameters.

CreateJobRequest

public CreateJobRequest(String endpoint,
                        String requestEncoding,
                        ByteBuffer data,
                        String dataStr,
                        Map<String,String> options)

Constructs a CreateJobRequest object with the specified parameters.

Parameters:

endpoint - Indicates which endpoint to execute, e.g. '/alter/table'.

requestEncoding - The encoding of the request payload for the job. Supported values:

• BINARY
• JSON
• SNAPPY

The default value is BINARY.

data - Binary-encoded payload for the job to be run asynchronously. The payload must contain the relevant input parameters for the endpoint indicated in endpoint. Please see the documentation for the appropriate endpoint to see what values must (or can) be specified. If this parameter is used, then requestEncoding must be BINARY or SNAPPY.

dataStr - JSON-encoded payload for the job to be run asynchronously. The payload must contain the relevant input parameters for the endpoint indicated in endpoint. Please see the documentation for the appropriate endpoint to see what values must (or can) be specified. If this parameter is used, then requestEncoding must be JSON.

options - Optional parameters.

• JOB_TAG: Tag to use for submitted job. The same tag could be used on backup cluster to retrieve response for the job. Tags can use letter, numbers, '_' and '-'

The default value is an empty Map.
