In this rollover scenario, an application writes data to only one file, for example,
. When the rollover occurs, based on the criteria, the application renames the file as
and continues to write to
. In this scenario, configure the File source service to read from
file. Specify the following properties for the File source service:
Name. Name for the file source service.
Directory. Path to the directory where the source files are located.
File Name. Name of the active file.
Delimiter. Delimiter that separates entries in the source file.
In this rollover scenario, when you undeploy the data flow or stop the EDS Node mapped to the file source, the application continues to write to the active file
. When rollover occurs, the application creates new files. When you redeploy the data flow or start the EDS Node, the source service continues to read from the
file and the data in the rolled over files is not read.
When the data flow is deployed and the source service is reading from the
file, if the application performs a rapid rollover, then the data in the rolled over files is not read.
