Use Neo4jv4 components instead. These properties are used to configure tNeo4jBatchSchema running in the Standard Job framework. The Standard tNeo4jBatchSchema component belongs to the Big Data and the Databases NoSQL families. The component in this framework is available in all Talend products with Big Data and in Talend Data Fabric. ## Basic settings | Properties | Description | | --- | --- | | 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.

This component supports Neo4j version V3.2.X only and does not support the remote mode. Therefore, do not reuse the connection to versions other than V3.2.X defined in a tNeo4jConnection component and do not select the Remote server check box in tNeo4jConnection.

Do
not use a 2.X.X version and a 3.X.X version in the same Job. Otherwise,
class conflict issues occur. | | Database path | Specify the directory to hold your data files. If the specified
directory does not exist, it will be created.

This field
appears only if you do not select the Use an
existing connection check box. | | Shutdown after
job | Select this check box to shutdown the Neo4j database connection when no more
operations on Neo4j are going to be performed after the current
component.

Alternatively, you can use tNeo4jClose to shutdown the
database.

This avoids errors such as "Id file not properly shutdown" at next execution
of Jobs involving Neo4j.

This check box is available only if the Use an existing
connection check box is not selected. | | Schema definition | Add indexes and unique property constraints to define the schema:

| ## Advanced settings | Properties | Description | | --- | --- | | Neo4j configuration | Add parameters to the table to configure the database to be created.

When entering values, use the syntax demonstrated by the examples given alongside the column names of this Nodes files table. | | tStatCatcher Statistics | Select this checkbox to gather the Job processing metadata at the Job level
as well as at each component level. | ## Global Variables | Variables | Description | | --- | --- | | Global Variables | NB\_LINE: the number
of rows read by an input component or transferred to an output component. This is an
After variable and it returns an integer.


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 checkbox is
cleared, if the component has this checkbox.

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