Before
Asynchronous to process large amount of data
• @Future
• Batch Jobs
• Schedule Jobs
• Which
options do
we have?
What is it?

Before
• The methods execute when
Salesforce has available
resources
• @future only
returns void type
• No job ID for @future jobs
• Parameters must be @Future
primitive data types
We can’t monitor
the future jobs
• Future methods must
be static methods
• The method does not
necessarily execute in
the same order is
called

Before
public with sharing class FutureClass {
@future
static void myMethod(String a, Integer i) {
System.debug('Method called with: ' + a + ' and ' + i+'... and I loved the sunny days :)');
// Perform long-running code
}
}

Before:
Batch Jobs
Before
• Database.executeBatch
returns Id
• We can monitor the batch jobs
• We can’t order
batch jobs
• Only 5 active jobs are
allow in the queue at the
same time ( //show error )
• Interfaces that we can
override in order to
process data
• Recursive calls
• Possibility to use iterator
– process different objet
type in the same batch

BBeefofroer: e
public class UpdateAccountFields implements Database.Batchable<sObject>{
public final String Query; public final String Entity;
public final String Field; public final String Value;
public UpdateAccountFields(String q, String e, String f, String v){
Query=q; Entity=e; Field=f;Value=v;
}
public Database.QueryLocator start(Database.BatchableContext BC){
return Database.getQueryLocator(query);
}
public void execute(Database.BatchableContext BC,
List<sObject> scope){
for(Sobject s : scope){s.put(Field,Value);
} update scope;
}
public void finish(Database.BatchableContext BC){
}
}

and Now..
@Future F l e x Q u e u e Batch

and Now..
Asynchronous
• @Future
• Batch Jobs : With FlexQue
• Schedule Jobs
• Queueable Interface

Flex Queue
More than 5 Apex Jobs
More than 5 Apex Jobs in the Apex Jobs Table
5 Apex Jobs Processing + 95 Apex Jobs Holding
New UI to monitor and manage the Apex Jobs in Holding Status
Reorder the holding Apex Jobs
Now

Flex Queue
Now
Show me!

Flex Queue
Now
I don’t believe you, show that!

Flex Queue
Now
Where is it? How does it work?!

Flex Queue
Reorder the holding Apex Jobs
Now
Lets reorder then!

Flex Queue
Then
Maybe you are thinking now…
• Schedule Jobs: do they work in the same way?
Yes, everything continues exactly the same. The benefit is now we can
schedule and run jobs that call apex jobs having the benefit of Flex Queue
that allow us to set the Batch in Holding status
• Can I reorder using any apex Method?
• Can I abort the Holding Jobs by UI or using System.Abort?

Taking
Care!!
With a big power became a big responsibility
• Only re order when necessary
• If there are batch jobs that are dependent to others!
• If there are chaining batch jobs

Extra
public class AsyncExecutionExample implements Queueable {
public void execute(QueueableContext context) {
Account a = new Account(Name='Acme',Phone='(415) 555-1212');
insert a;
}
}
Submit and Monitor Jobs for Asynchronous
Execution with the Queueable Interface
ID jobID = System.enqueueJob(new AsyncExecutionExample());
AsyncApexJob jobInfo = [SELECT Status,NumberOfErrors FROM AsyncApexJob WHERE
Id=:jobID];
