SSIS ODBC Source not closing connection to Cassandra

  • Hi there,

    I have to load data from a CassandraDB.

    I am using the datastax odbc-driver in SSIS (2014) and I have following situation

    The package connects to the database, loads the data, does everything else in the ssis-package but the sql server agent won't finish the package.

    In debug-mode it "seems" to work fine, but you see that the DtsDebugHost.exe is still running after you finished the debug mode.

    I tried a few angles to solve this and what I can see in the cassandra-monitoring the connection remains open.

    I ended in writing an script source where I acquire and close the connection and this works fine.

    The connection is closed properly and in Debug and Agent it works fine.

    I didn't test yet, if this script source is slower or faster, however it much harder to maintain.

    My question would be:

    Can I somehow force the odbc-source to close the connection properly or

    if it is not possible to create a script-task that would close the connection to the (ODBC)-cassandra-source explicitly at the end of the package, so I can use the build-in odbc data source?
