Dwaine Gilmer, John Taylor and Matthew Yipp wrote a whitepaper filled with best practices for working with the SQL Adapter. For the best performance, the white paper says you must:
- Design the mapping of data in the tables of the database to message in BizTalk Server.
- Define how the mapping of the data to a BizTalk message takes place.
- Determine the message size and the level of concurrency when accessing the stored data.
- Carefully design, craft, and implement the SQL statements that provide and consume data.
Issues and solutions around these performance issues are addressed in the paper. Download it at http://download.microsoft.com/download/5/0/f/50f397a7-13c7-4807-bd51-66db5f5b0908/best%20practices%20for%20the%20sql%20adapter.doc.
