WHAT IS BATCH APEX IN SALESFORCE?

• Batch Apex is an asynchronous execution of apex
  code in Salesforce.
• It allows you to define a single job that can be
  divided into manageable chunks, where query
  chunks can be processed separately.
• Batch Apex is used to process many records.
• It will retrieve all the records you want to
  update or perform operations.

WHEN TO USE BATCH APEX?

• You can go to Batch Apex when you want to process
  many records daily or even at regular intervals.
• Also, you can apply a batch apex when you want an
  asynchronous operation.
• Batch Apex is revealed as an interface that the
  developer must implement.

  Apex. Batchable (Salesforce-provided) interface,
  followed by programmatic invoking of the class.
• Batch Apex work on more than 10,000 records,
  because it divides them into sub-tasks, wherever
  every subtask may contain up to 2000 records.

WHAT IS DATABASE.BATCHABLE INTERFACE?

• To use Batch Apex, you must write the Apex class
  that applies to the Database. Batchable
  Interface. The Database.Batchable Interface
  consists of three methods, which should be
  implemented, as follows
• The Start Method
• Execute Method
• Finish Method

WHAT IS A DATABASE.BATCHABLE INTERFACE?

• Batches of records typically execute in the order
  that they are received from the start method.
• The order in which batches of records execute, on
  the other hand, is determined by a variety of
  factors.
