A Hyper-Fast Batchable Interface for Salesforce

Apex Database.Batchable

Why HyperBatch?Speed!

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.

Why HyperBatch?Speed!

CreateContactsBatch• Using traditional Apex Database.Batchable: 45 mins

Why HyperBatch?Speed!

UpdateContactsBatch• Using traditional Apex Database.Batchable: 10 mins

Why HyperBatch?Speed!

DeleteContactsBatch• Using traditional Apex Database.Batchable: 33 mins total (got row lock errors,

had to run twice)

Why HyperBatch?Speed!

CreateContactsHyperBatch• Using HyperBatch• 2 mins 12 seconds

DeleteContactsHyperBatch• Using HyperBatch• 3 mins 15 seconds• RowLock / retry• 9500 Batch Size

DeleteContacts 33 3.25 29.8 10.9%Total 88 5.55 82.5 6.7%

Why HyperBatch?Speed!

Summary• Running all 3 example batch jobs takes only 6 mins instead of 88 mins.• You save 82 mins.• It only takes 6.7% of the time!

Why HyperBatch?User Experience

Why HyperBatch?Concurrency

Asynchronous • Apex Batch

• 5 running per org• HyperBatch

• Not subject to 50 job per transaction limit (each request is a new transaction)Synchronous• Apex Batch

• N/A• HyperBatch

• 10 long running per org, unlimited otherwise

Why HyperBatch?Concurrency

Why HyperBatch?Concurrency

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 succeeds. Each

re-attempt gets a new context!

How it WorksSummary

• 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.• Wrapping requests in unique identifiers for closed loop execution – JavaScript function binding.• Each execute can return some state of type Object, it can be anything.• Async

• Parallel remote actions fire the qeueables for the batch executions methods. (Not serial!)• JavaScript polls for the status of the qeueables, waiting for them to complete.• Execute state is stored in a custom object, and a list of them is returned to the finish() method,

then they are deleted.• Sync

• Parallel remote actions fire the synchronous transactions. (Not serial!)• Execute state is returned synchronously and stored in JavaScript in the browser until they are

all complete.

New Features

• Synchronous mode• Batch Size Control• Test Methods

Roadmap

• Throttle requests (x number of open connections)• Enhance the user interface• 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
