What is Object Pooling?

[Martinricky]

keep a pool of objects in memory to be re-used later and hence it will reduce the load of object creation to a great extent. Whenever there is a request for a new object, the pool manager will take the request and it will be served by allocating an object from the pool. Pooling basically means utilizing the resources efficiently, by limiting access of the objects to only the period the client requires it.

An object pool is a collection of a particular object that an application will create and keep on hand for those situations where creating each instance is expensive. A good example would be a database connection or a worker thread

Object pooling allows the sharing of instantiated objects.

Object pooling is an automatic service that allows a pool of active component instances to be maintained for usage by any requesting client.

Object pooling provides a repository of active and ready-made objects that may be used by clients requesting configured pooling components. Pool objects may be configured and monitored by specifying required options, such as pool size and time-out value for object creation.

Pooling basically means utilizing the resources efficiently,by limiting access of the objects to only the period the client requires it.

Increasing utilization through pooling usually increases system performance.
Object pooling is a way to manage access to a finite set of objects among competing clients.
In other words,object pooling is nothing but sharing of objects between different clients.

Since object pooling allows sharing of objects ,the other clients/processes need to re-instantiate the object(which decreases the load time), instead they can use an existing object.
After the usage , the objects are returned to the pool.

good information thanks for sharing.

Object pooling is a one type of collection of particular object that we can use create an object and keep hand for those situation where creating each instance is expensive.

[Shivangi Panwar]

An object pool is any collection of object which are recycled, rather than recreated each time they are needed.

The object pool pattern is a software creational design pattern that uses a set of initialized objects kept ready to use – a "pool" – rather than allocating and destroying them on demand. A client of the pool will request an object from the pool and perform operations on the returned object.

The idea of object pooling is similar to the operation of your local library. When you want to read a book, you know that it's cheaper to borrow a copy from the library rather than purchase your own copy. Likewise, it is cheaper (in relation to memory and speed) for a process to borrow an object rather than create its own copy. In other words, the books in the library represent objects and the library patrons represent the processes. When a process needs an object, it checks out a copy from an object pool rather than instantiate a new one. The process then returns the object to the pool when it is no longer needed.
