Component family

Big Data/MemSQL

 

Function

This component opens a connection to the MemSQL database to be used.

Purpose

This component is used to open a connection to the specified database that can then be reused in the subsequent subjob or subjobs.

Basic settings

Property type

Either Built-in or Repository.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

 

 

Built-in: No property data stored centrally.

 

 

Repository: Select the repository file in which the properties are stored. The fields that follow are completed automatically using the data retrieved.

 

Host

Enter the location of the database server to be used.

 

Port

Enter the listening port number of the database server to be used.

 

Database

Enter the name of the database to be used.

 

Username and Password

DB user authentication data.

 

Use or register a shared DB Connection

Select this check box to share your connection or fetch a connection shared by a parent or child Job. This allows you to share one single database connection among several connection components of the same database type from different Job levels that can be either parent or child.

Warning

This option is incompatible with the Use dynamic job and Use an independent process to run subjob options of the tRunJob component. Using a shared connection together with a tRunJob component with either of these two options enabled will cause your Job to fail.

Shared DB Connection Name: set or type in the shared connection name.

Advanced settings

Additional JDBC parameters

Specify additional connection properties for the DB connection you are creating.

 

tStatCatcher Statistics

Select this check box to gather the job processing metadata at a Job level as well as at each component level.

Global Variables 

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage

This component is more commonly used with other MemSQL components.

Log4j

If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.

For more information on the log4j logging levels, see the Apache documentation at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html.
