Hi Spring fans! In this installment we look at distributed locks in Spring Integration to ensure exclusive access to a shared resource in a cluster.

Great job as always Josh! I just today highlighted this video to one of my colleagues as an example of an excellent developer-oriented video.

[@JimzZel]

Thank you for this video, I learned something today.

"Using my second favorite place.. start.....stackoverflow..." 0:55, haha , we know what You are made of :> (Good tutorial)

[@hannesvideo]

Ok, not much spring-integration here, I thought. But it is the LockRegistry that is used!

[@khalildureidy]

is it supposed to create the db tables automatically for the lock? or you created them manually?

[@aniyt10]

Good point.
I had to create this table
CREATE TABLE INT_LOCK (
LOCK_KEY CHAR(36) NOT NULL,
REGION VARCHAR(100) NOT NULL,
CLIENT_ID CHAR(36),
CREATED_DATE TIMESTAMP NOT NULL,
constraint INT_LOCK_PK primary key (LOCK_KEY, REGION)
);

[@rajpraveenbhiwani9176]

With differenct JVMs will that solution work. And if not how can we handle?

[@shubhamna1192]

getting initialization error for the final field ,private final LockRegistry registry;

[@vishalsundararajan1228]

I want a queuing approach instead of locking it, i want all the request to be processed but only one at a time

[@WasifTanveer]

You can use some broker i.e. publisher consumer mechanism to achieve your requirement

[@smithdragon6477]

Good demo .but no transaction controls ...

[@valix85]

Please in future increase font zoom in IDE and browser... Good video

[@arvindgurav9911]

Can you share github repo link.

[@andreslascano]

How can I do this with mongodb?

[@srvmojo9190]

Theres good support for the same in spring data , using @Version annontation & optimistic locking or pessimistic locking even for clustered environment .

[@waqasrana7891]

@@srvmojo9190 that will throw exception so you have to retry again

[@himanshurawal7223]

Please increase the font

[@hongxing7259]

do NOT use verb in api uri, like "update", and do use correct http method PUT for update

[@janbodnar7815]

Arrgh, dark theme please.

[@zapl80]

No, please stay with the light theme. Stupid pseudo pro dark look doesn't make your code better nor is it easier to read.

[@janbodnar7815]

@@zapl80 How old are you? Because the older you are, the more you appreciate the dark theme; it is easier on the eyes.

[@lisafox9026]

NO dark theme !!!! bad video!!!!! beeeee
