Salesforce Bulk API

Bulk API is based on REST and is used for processing large sets of data. It allowes to Query, Insert, Update, Upsert or Delete large no. of records asynchronously by submitting batches. On the other hand hand SOAP API is used in real time applications that processes a small no. of records. Although SOAP API can also be used to process large sets of data but it becomes less practical to use SOAP API instead of Bulk API when processing large no. of data is desirable.
