I had a chance to attempt a question raised on stackoverflow regarding moving data from SQL Server to MySQL using NiFi. The user is using GenerateTableFetch to read data from SQL Server and then try to use LOAD DATA command in ExecuteSQL but this involves writing the read SQL Server data to filesystem and then load it, which is a performance hit, I suggested the user to try PutDatabaseRecord but I have never tried the approach myself and going by the docs, I think it won't show any performance benefit than LOAD DATA because the former reads from file and inserts at a high speed while the latter reads content and parses it according to the configured Record Reader and insert the rows as a single batch. Confused, I wanted to get the community's opinion/thoughts on this. Please attempt the questions, if you have better suggestions.
