Hi,
I have created a package that extracts data(just extracting, no transformations) from a MySQL Server to a MS SQL Server 2012 database. There are a handful of tables which a few milion records (max ist 14 mio). I use ADO.Net source to get the data from the MySQL database.
I have following problem: I think the performance is not so good when the package wants to extract the larger tables. When I run the package in SSDT I can see that the Ado.Net Source Adapter is busy with extracting but I have to wait nearly 10 min until
the first rows are going from the source to the destination. It seems for me as if the source adapter waits until it received all the rows from MySQL. After waiting i just have to wait a minute or less until the rows were written to the destination table.
This is the first time I have to deal with MySQL. Is there anything I can do to speed up the process (I have read access to MySQL only)? When I have a SQL Server as a source I don't have to wait so long until the first rows are written. So is MySQL able to deliver in batches or something else?
Thanks
Patrick
