Class RawInsertRecordsRequest

java.lang.Object

com.gpudb.protocol.RawInsertRecordsRequest

All Implemented Interfaces:

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

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

A set of parameters for GPUdb.insertRecordsRaw(RawInsertRecordsRequest).

Adds multiple records to the specified table. The operation is synchronous, meaning that a response will not be returned until all the records are fully inserted and available. The response payload provides the counts of the number of records actually inserted and/or updated, and can provide the unique identifier of each added record.

The options parameter can be used to customize this function's behavior.

The update_on_existing_pk option specifies the record collision policy for inserting into a table with a primary key, but is ignored if no primary key exists.

The return_record_ids option indicates that the database should return the unique identifiers of inserted records.

The route_to_address option directs that inserted records should be targeted for a particular database node.

Constructor Detail

RawInsertRecordsRequest

public RawInsertRecordsRequest()

Constructs a RawInsertRecordsRequest object with default parameters.

RawInsertRecordsRequest

public RawInsertRecordsRequest(String tableName,
                       List<ByteBuffer> list,
                       Map<String,String> options)

Constructs a RawInsertRecordsRequest object with the specified parameters.

Parameters:

tableName - Table to which the records are to be added. Must be an existing table.

list - An array of binary-encoded data for the records to be added. All records must be of the same type as that of the table. Empty array if listEncoding is json.

options - Optional parameters.

• UPDATE_ON_EXISTING_PK: Specifies the record collision policy for inserting into a table with a primary key. If set to true, any existing table record with primary key values that match those of a record being inserted will be replaced by that new record. If set to false, any existing table record with primary key values that match those of a record being inserted will remain unchanged and the new record discarded. If the specified table does not have a primary key, then this option is ignored. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• RETURN_RECORD_IDS: If true then return the internal record id along for each inserted record. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• ROUTE_TO_ADDRESS: Route to a specific rank/tom. Option not suitable for tables using primary/shard keys

listEncoding - The encoding of the records to be inserted. Supported values:

• BINARY
• JSON

The default value is BINARY.

options - Optional parameters.

• UPDATE_ON_EXISTING_PK: Specifies the record collision policy for inserting into a table with a primary key. If set to true, any existing table record with primary key values that match those of a record being inserted will be replaced by that new record. If set to false, any existing table record with primary key values that match those of a record being inserted will remain unchanged and the new record discarded. If the specified table does not have a primary key, then this option is ignored. Supported values:
