Performance Best Practices for Preloading

Use the following best practices when you use preload:

  • Size the cache according to the requirements (number of records to be preloaded, size of records, percentage of synchronized records). Refer to TIBCO MDM Cache Calculation.
  • Enable the preload tranche for preloading large volumes of data.
  • Set preload tranche size high for preloading large volumes of data. Tranche enables quick loading of the data from a single repository by splitting the records of the repository in portions and initiating the load for each portion in parallel.

    The tranche is set to 500000 in the performance lab for 35 million records preloading.

For more information on the preload properties, refer to the Configuring Preload Properties section in TIBCO System Administration.

Preloading is an asynchronous activity. After you initiate preloading, JMS messages are queued up on the ASYNCH queue. An increase in the number of listeners or TIBCO MDM members increases the processing speed. Preloading also supports clustering.
