tPostgresqlOutputBulkExec

Improves performance during Insert operations to a Postgresql database.

The tPostgresqlOutputBulkExec executes the Insert action on the data provided.

The tPostgresqlOutputBulk and tPostgresqlBulkExec components are generally used together as part of a two step process. In the first step, an output file is generated. In the second step, this file is used in the INSERT operation used to feed a database. These two steps are fused together in the tPostgresqlOutputBulkExec component.

tPostgresqlOutputBulkExec Standard properties

These properties are used to configure tPostgresqlOutputBulkExec running in the Standard Job framework.

The Standard tPostgresqlOutputBulkExec component belongs to the Databases family.

The component in this framework is available in all Talend products.

Note: This component is a specific version of a dynamic database connector. The properties related to database settings vary depending on your database type selection. For more information about dynamic database connectors, see DB Generic components.

This component supports PostgreSQL vector data types. Use the VECTOR or Dynamic DB type in your schema column definition to store and then query vector embeddings. For more information about pgvector, read the Amazon documentation.

Basic settings

Properties	Description
Database	Select the desired database type from the list and click Apply.
Property type	Either Built-in or Repository Built-In: You create and store the schema locally for this component only. Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs. When the schema to be reused has default values that are integers or functions, ensure that these default values are not enclosed within quotation marks. If they are, you must remove the quotation marks manually. For more information, see Retrieving table schemas.
Use an existing connection	Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.
DB Version	Select the database version in the dropdown list.
Host	Enter the database server IP address.
Port	Listening port number of DB server.
Database	Enter the name of the database.
Schema	Enter the name of the PostgreSQL schema.
Username and Password	Enter the database user authentication data. To enter the password, click the [...] button next to the password field, enter the password in double quotes in the pop-up dialog box, and click OK to save the settings.
Table	Enter the name of the table to be written. Note that only one table can be written at a time and that the table must exist for the insert operation to succeed.
Action on table	Select the operation to be performed on the defined table: None: No operation is carried out. Drop and create table: The table is removed and created again. Create table: The table does not exist and gets created. Create table if not exists: The table is created if it does not exist. Drop table if exists and create: The table is removed if already exists and created again. Clear a table: The table content is deleted.
File Name	Enter the name of the file to be generated and loaded. Information noteWarning: This file is generated on the machine specified by the URI in the Host field and it should be on the same machine as the database server.
Schema and Edit Schema	A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either Built-in or stored remotely in the Repository. Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available: View schema: choose this option to view the schema only. Change to built-in property: choose this option to change the schema to Built-in for local changes. Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window. This component supports PostgreSQL vector data types. Use the VECTOR or Dynamic DB type in your schema column definition to store and then query vector embeddings. For more information about pgvector, read the Amazon documentation.

Advanced settings

Properties	Description
Additional JDBC Parameters	Specify additional JDBC parameters for the database connection created.
Action on data	Select the action to be performed on the table data: Bulk Insert: Add multiple entries to the table. If duplicates are found, the Job stops. Bulk Update: Make simultaneous changes to multiple entries.
Copy the OID for each row	Retrieve the ID item for each row.
Contains a header line with the names of each column in the file	Specify that the table contains header.
Use local file for copy (for DB server 8.2 or newer)	(Enabled by default) Select this check box to copy files from the PostgreSQL client machine.
Encoding	Select the encoding standard from the list, or select CUSTOM and define it manually. This field is compulsory for DB data handling.
File type	Select the type of file being handled.
Null string	String displayed to indicate that the value is null.
Row separator	String (ex: "\n"on Unix) to distinguish rows.
Fields terminated by	Character, string, or regular expression to separate fields.
Escape char	Character of the row to be escaped.
Text enclosure	Character used to enclose text.
Activate standard_conforming_string	Activate the variable.
Force not null for columns	Define the column nullability. Force not null: Select the checkbox next to the column you want to define as not null.
tStatCatcher Statistics	Select this checkbox to collect log data at the component level.
Enable parallel execution	Select this check box to perform high-speed data processing, by treating multiple data flows simultaneously. Note that this feature depends on the database or the application ability to handle multiple inserts in parallel as well as the number of CPU affected. In the Number of parallel executions field, either: Enter the number of parallel executions desired. Press Ctrl+Space and select the appropriate context variable from the list. For further information about context variables, see Using contexts and variables. Note that when parallel execution is enabled, it is not possible to use global variables to retrieve return values in a subJob. The Action on table field is not available with the parallelization function. Therefore, you must use a tCreateTable component if you want to create a table. When parallel execution is enabled, it is not possible to use global variables to retrieve return values in a subJob.

Usage

Usage guidance	Description
Usage rule	This component is mainly used when no particular transformation is required on the data to be loaded onto the database. This component supports PostgreSQL vector data types.
Limitation	The database server must be installed on the same machine where Talend Studio is installed or where the Job using tPostgresqlOutputBulkExec is deployed, so that the component functions correctly.
