• Repeatable Streaming
Enabled by streaming contents
being saved to a temporal buffer.
This lets the user ignore streaming
position, streaming components at
time intervals, and stream
component consumption.

• Mule 4 now analyzes runtime conditions and makes adjustments
automatically.
• Achieves optimal performance without having to do manual tuning
steps, such as:
 Declaring exchange patterns.
 Processing strategies
 Threading configuration.

Simpler Batch module
39
• Now the scope can live
inside a flow.
• We no longer have
recordVars for batches.
You can now just use
flow variables directly.
This will save you bugs
and undesired behavior.
• Easier to understand.

Mule SDK

Mule SDK
46
The Mule SDK is the successor for Anypoint Connector Devkit.
• Allows extending Mule runtime with your own modules and
connectors.
• No more generated code
• Classloading isolation
• Consistent connect experience

47. All contents © MuleSoft Inc.
Migrating from DevKit
47
• Anypoint Connector DevKit is not compatible with Mule 4.
• DevKit migration tool (https://docs.mulesoft.com/mule-
sdk/v/1.1/dmt)
 A new project will be generated which adapts your existing code into an SDK
compatible Project (it will still require your review and adjustment)

Frictionless upgrades

Classloader isolation
49
• Runtime, and Anypoint Connectors, any library changes that occur
internally do not affect the application itself.
• Connectors are distributed outside the runtime as well, making it
possible to get connector enhancements and fixes without having to
upgrade the runtime or vice versa.

Frequently asked questions
50
• Is the Mule 4 available on CloudHub?
Yes! Mule 4 is already available and ready to deploy.
• Is Studio 7 compatible with Mule 3.x?
No. You must use Studio 6 to open 3.x projects. Similarly, if you
want to deploy applications on Mule 4.0, you must compose those
applications in either Anypoint Studio 7.0 or Anypoint Design Center -
flow designer.
