A Hyper-Fast Batchable Interface for Salesforce

2. Apex Database.Batchable

3. ​Case study: Account / Contact Batches
• Prerequisite: 121K Accounts already in the system
• CreateContactsBatch: Creates 3 Contacts for each Account with a random “probability” field for
each. 363k Contacts total.
• UpdateAccountsBatch: For each Account, update the highest and lowest probability on the Account
by querying the child Contacts. Get the overall highest and lowest probability across all the
Accounts.
• DeleteContactsBatch: Delete all of the Contacts in the system. Keep a running total of how many
get deleted.
Speed!
Why HyperBatch?

​Using traditional Apex Database.Batchable: 45 mins

5. ​UpdateContactsBatch
​Using traditional Apex Database.Batchable: 10 mins
Speed!
Why HyperBatch?

6. ​DeleteContactsBatch
​Using traditional Apex Database.Batchable: 33 mins total (got row lock errors, had to run twice)
Speed!

Operation Database.Batchable HyperBatch Difference Percentage
CreateContacts 45 2.2 42.8 4.9%
UpdateContacts 10 0.6 9.4 6.3%
DeleteContacts 33 1.2 28 3.6%
Total 88 4 84 4.6%

11. ​Summary
​Running all 3 example batch jobs takes only 4 mins instead of
88 mins.
​You save 84 mins.
​It only takes 4.6% of the time!
Speed!

13. Concurrency
Why HyperBatch?
​Max concurrent jobs processing
​Apex Batch: 5 per org
​HyperBatch: ? 20 / user?

14. Concurrency
Why HyperBatch?
​Row lock behavior
​Apex Batch: default is a failed batch execution. Retry logic can be built, but it will likely exceed the
transaction limits.
​HyperBatch: row locks retry automatically until the transaction succeed. Each re-attempt gets a new
context!

15. Summary
How it works
• HyperBatch interface that mimics the Database.Batchable interface.
• Browser orchestration for selecting jobs and running them on-demand.
• Lightning Design System, Visualforce (Lightning Components would be a data bottleneck).
• AJAX toolkit for PK chunking the query locator.
• Parallel remote actions fire the qeueables for the batch executions methods. (Not serial!)
• Wrapping requests in unique identifiers for closed loop execution – JavaScript function binding.
• JavaScript polls for the status of the qeueables, waiting for them to complete.
• Each execute can return some state of type Object, it can be anything. These are stored in a
custom object, and a list of them is returned to the finish() method, then they are deleted.

19. Roadmap
• Enhance the user interface
• Test methods
• Support custom iterators instead of just query locator
• Support simple data operations like update a field or delete records without having to write Apex
• Chunk in 2 dimensions: (Parent Id, then Record Id) to avoid row lock errors
