MySQLDataWriter loads data into a database table using native MySQL database client.
It reads data either from the input port or from an input file.
You can attach the optional output port and read records which have been reported as rejected.
Reading from input port (input port connected)
dumps the data into a temporary file which is then used by
utility. You can set the temporary file explicitly by setting the
Loader input file attribute or leave it blank to use default.
Reading from a file (no input connected)
uses the Loader input file attribute as a path to
your data file. The attribute is mandatory in this case.
The file needs to be in a format recognized by the
utility (see MySQL LOAD DATA).
This component executes the MySQL native command-line client
The client must be installed on the same machine as the graph is running on.
MySQLDataWriter is a bulk loader suitable for
uploading many records to database.
To insert several records, you can also use DBOutputTable,
which does not require
The name of a command file containing the
INFILE statement (See MySQL LOAD DATA),
If it is not set, the command file is created in CloverDX temporary directory and it is deleted after the load finishes.
If it is set, but the specified command file does not exist, a temporary command file is created with the specified name and path and it is not deleted after the load finishes.
If it is set and the specified command file exists, this file is used instead of command file created by CloverDX.
The name of an input file to be loaded, including the path.
If it is not set, a loader file is created in CloverDX or OS temporary directory (on Windows) or stdin is used instead of temporary file (on Unix). The file is deleted after the load finishes.
If it is set, a specified file is created. It is not deleted after data is loaded and it is overwritten on each graph run.
If the input port is not connected, this file must be specified, must exist and must contain data that should be loaded into the database. The file is not deleted nor overwritten.
You should not write maps and lists.
