What is PLINQ?

PLINQ stands for Parallel Language Integrated Query. It is the parallel execution of LINQ, in which a query can be implemented by using multiple processors. PLINQ ensures the scalability of software on parallel processors in the execution environment. It is used where data grows fast, such as in telecom industry or where data is heterogeneous.

PLINQ also handles all the operators of LINQ. In addition, you can query 'collections by using PLINQ. It can also run several LINQ queries concurrently and makes use of the processors on the system. Apart from this, PLINQ uses parallel execution, which helps in running the queries rapidly. Parallel execution provides a major performance improvement to PLINQ over certain types of legacy code, which takes too much time to implement.
