QUESTION POSED ON: 23 December 2005
We are fine-tuning our banking system business application to reduce bandwidth use for online real-time transactions processing.

If we change one record in one table (under a merged replication scenario), do we push the whole database? Or do we push that one table with the change? Or only the changed record?


>
EXPERT RESPONSE
This change would be based on how the subscription is set up. Review the subscription settings to see which data is being replicated. The easiest means to do so is in Enterprise Manager. Reference the following article for additional tips: Merge Replication Performance Tuning and Optimization.
