SSIS, as an ETL tool offers the ability to merge structured and unstructured data by importing Hive data into SQL Server and apply powerful analytics on the integrated data. ETL is a process to extract data, mostly from different types of systems, transform it into a structure that’s more appropriate for reporting and analysis and finally load it into the database. One of these BI components is an Extract, Transform, and Load (ETL) tool called SQL Server Integration Services (SSIS).
The advantage that SQL Server brings is that it offers a powerful Business Intelligence (BI) stack, which provides rich features for data mining and interactive reporting. As discussed in Chapter 1, it has become extremely important these days to integrate data between different sources. Microsoft SQL Server is a complete suite of tools that include a relational database management system (RDBMS), multidimensional online analytical processing (OLAP) and tabular database engines, a brokering service, a scheduling service ( SQL Agent), and many other features. This property setting can cause the running package to stop responding.
Because the origi- nal default value has to be updated for better results, a warning message like this is given to the user calling for an action: “The Maximum insert commit size property of the OLE DB destination “OLE DB Destination” is set to 0. In this case, the default value of FastLoadMax InsertCommitSize property in this component was changed from 0 to 2147483647.

The message given to user as a result of OLE DB Destination component upgrade from the Integration Services 2005 package to a later ver- sion like SSIS 2012 is an example of this type of warning. The second type of warning is an actionable warning, which requires SSIS package developers to take a specific action. You do not have to do anything on the package but might have to plan on additional upgrade validation or just be prepared to deal with any issues that might arise dur- ing execution of the upgraded package. Involving the upgrade of an SSIS 2008 Script task would look like this: Warning: Script Task: Found SQL Server Integration Services 2008 Script Task “ST_f28de6465e5e4834a00c4a07f76d879b” that re- quires migration! If there are no errors reported during the upgrade of a Script task, then most likely the upgrade process succeeded with package updates, but because the scripting engine used during package execution would change between the older and newer version of packages, you need to be aware of this major change.
