Designing Applications for Batch Processing
If your Pathway application includes batch processing, consider the different needs of this type of
processing in your design.
For example, you might code a Pathsend program that takes its input from a file rather than from
a terminal, then sends requests to a server to make updates to a database. This program could be
configured as a server, therefore operating as a nested server. Its input file might be TMF protected,
and the Pathsend program might make updates to it.
An application that does several updates to a database, with each update coded as a separate
TMF transaction, could be slow when it performs these updates as a batch job rather than performing
them online. For batch processing, it is usually faster to group a number of updates in a single
transaction. However, if your batch jobs are very large, note that you should not try to group more
than about one thousand updates in one TMF transaction.
