Class InsertRecordsRequest<T>

java.lang.Object

com.gpudb.protocol.InsertRecordsRequest<T>

Type Parameters:

T - The type of object being processed.

public class InsertRecordsRequest<T>
extends Object

A set of parameters for GPUdb.insertRecords(InsertRecordsRequest).

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.

Constructor Detail

InsertRecordsRequest

public InsertRecordsRequest()

Constructs an InsertRecordsRequest object with default parameters.

InsertRecordsRequest

public InsertRecordsRequest(String tableName,
                            List<T> data,
                            Map<String,String> options)

Constructs an InsertRecordsRequest object with the specified parameters.

Parameters:

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

data - 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.
• TRUNCATE_STRINGS: If set to true, any strings which are too long for their target charN string columns will be truncated to fit. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• RETURN_INDIVIDUAL_ERRORS: If set to true, success will always be returned, and any errors found will be included in the info map. The "bad_record_indices" entry is a comma-separated list of bad records (0-based). And if so, there will also be an "error_N" entry for each record with an error, where N is the index (0-based). Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• ALLOW_PARTIAL_BATCH: If set to true, all correct records will be inserted and incorrect records will be rejected and reported. Otherwise, the entire batch will be rejected if any records are incorrect. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• DRY_RUN: If set to true, no data will be saved and any errors will be returned. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.

The default value is an empty Map.
