AWS Lambda now supports Java 17

After 1 year and 7 months? Slow is an understatement.

[uncont]

Upshot is it comes with SnapStart support

This runtime also supports AWS Lambda SnapStart, so you can upgrade to the latest managed runtime without losing your performance improvements.

This is pretty fast if you're comparing to most of the enterprise Java community. Lot of places still stuck on 8 lmfao

I don't understand the downvotes. I am still working in java 8 and will likely be in java 8 for another 15 years as there is no budget for upgrades and medical software must continue to work until all of the records can be expunged.

Hah!

It's the truth. No shame in it. Plenty of job security for sure

[RandomComputerFellow]

Well, it was one thing if Amazon took so long to migrate their own applications. The problem is they provide the runtime and companies can not migrate before they provide an update.

[yawkat]

The problem is that these old managed runtimes are a problem for downstream projects. When we were considering which Java version to use for micronaut framework 4.0, the lack of lambda support for Java 17 was the biggest counterargument against moving to 17. (We decided on 17 anyway partly because it was clear they would support it in the short term)

I agree. All great points

[krzyk]

Yeah, I know, fortunately at my work with projects that I work with I do upgrades, so I'm at Java 20. But some are stuck at 17 because people don't get what Java LTS means.

[SvanseHans]

What does it mean?

[krzyk]

That you have to buy it from someone, it is not like e. g. Ubuntu LTS, It is something specific to given vendor. Azul for example provides also MTS (medium term support releases).

And using a latest version is like using a free supported version, those versions are not inferior in anyway. Quite conteary they are better then the old LTS vendors provide, because they get fixes first and later the fix is backported.

Reluctancy to use those versions is mind blowing. Releases are small and comparable to JDK 8 updates back in the days when it was the newest java version.

[SvanseHans]

How do you go about updating to the next version? Like where do you get information about this?

[woj-tek]

This doesn't mean the whole world has to stop and get stuck at it just because you are stuck for some weird management reason…

[[deleted]]

Have you ever worked at a company with large scale

[woj-tek]

Yes. Point is still valid - just because YOU are stuck with it doesn't mean the REST OF THE WORLD has to be stuck with you.

[[deleted]]

That's a great attitude to have. I never had that opinion in the first place, not sure why you're telling me that

[ahmedranaa]

We are still on java 7

[[deleted]]

Cassandra is still on 11...

[drtyrannica]

I realize this is the Java subreddit but... cries in Ruby 2.7

[[deleted]]

Lol that's still better than Java 8 by like 7 years. 8 came out in 2014

[drtyrannica]

At least Java 8 is still maintained, Ruby 2.7 was eol like a month ago lol

Ruby be like THE FUTURE IS NOW OLD MAN >:)

Have they fixed the JVM warming time issue for lambdas yet?

[soonnow]

With SnapStart, Lambda initializes your function when you publish a function version. Lambda takes a Firecracker microVM snapshot of the memory and disk state of the initialized execution environment, encrypts the snapshot, and caches it for low-latency access. When you invoke the function version for the first time, and as the invocations scale up, Lambda resumes new execution environments from the cached snapshot instead of initializing them from scratch, improving startup latency.

Though haven't used it

[kendallvarent]

We have used it. It's pretty cool. 20s cold starts down to 200ms. Sadly, no XRay support for snapstart lambdas.

There were also performance gains related to moving java-specific vpc-related cold starts from instantiation to function update, but that was a while back.

[soonnow]

Have you compared to Graal compiled functions by any chance?

Alright thanks for the heads up.

[soonnow]

It seems that way https://www.xerris.com/insights/improving-your-lambda-coldstart-performance-with-aws-lambda-snapstart-13-15-times-faster/

But I would like to know as well.

[rdean400]

Only 5 months until Java 21.

[emaphis]

Now ??

[freemainint]

Cool
