This is my first blog where I would like to share my experience on how to connect with SFDC via REST adapter using SFDC bulk API concept. (without BPM)

When to use Bulk API?

Bulk API is based on REST and is optimized for loading or deleting large sets of data. We can query, insert, update, upsert, or delete many records asynchronously by submitting batches. Salesforce processes batches in the background.  Bulk API is designed to make it simple to process data from a few thousand to millions of records.
