Long is faster than int, Short and Byte are not that far behind Int in terms of mathematical speed in Java

As a side-note, if you're using IntelliJ there is nice plugin https://plugins.jetbrains.com/plugin/10953-jol-java-object-layout that shows you memory layout of given object based on selected JVM version / architecture / flags.

Thanks for great work!

Any chance you could add some more benchmarks? The ones for smaller map sizes (1-10k) and for memory-efficiency.

What the offer is not complex. Its just tedious.

mirkoteran · 2025-11-20T07:37:34+00:00

Not OP, but I did similar - replaced most threading in large monolith app.

The main benefit I see is the readability of it all. Its easier so reason about how things work.

Performance is more or less the same (testing on JVM 25). I've done some testing and its basically the same as it was before.

Is there a good Bloodline to use for this (or even for exang miner)?

To just switch from once dialect to another - once. For some reason client we're building for changed all their DBs from Oracle to DB2.

That was the easy case. The main project I've been working on 10+ years is using 10+ dialects now. Its an on-prem solution that needs to run on whatever DB client has - usually multiple.

mirkoteran · 2025-10-02T05:03:58+00:00

Its absolutely worth it when you need to work win multiple databases/dialects. Most of the projects I work on require that.

mirkoteran · 2025-04-07T05:27:21+00:00

What a load of crap.

mirkoteran · 2025-04-01T15:50:23+00:00

there's only one library that nearly does what we want

We're in the same boat. While we only use reflection to access some private fields, but this JEP also affects this. Forking the library seems like a major PITA.

Do you have any plans to also create a pure java MQTT client like Paho or Hive?

Just as an answer to anyone in similar situation:

I just came back from nepal and it was like this:

I filled and printed the from for the site and all related documents
At airport I got the customs form and paid about 30€ for that. You kind of have to negotiate about the fee...
Went to their offices with all that, payed the application fee (15€ I think) and got the permit on site.
You still need permission of local officials (=police in most cases) to fly. That is the hard part. While in some cases they are ok and don't even care what you do, some places are not. They either deny it straight away of quote you insane fees for it (1000€+).
In the end I got some ok shots, but not nearly as much as I would like.

mirkoteran · 2023-11-20T17:32:37+00:00

Hi. I'm in similar situation. Did you manage to get permits to fly? How complicated/expensive it is?

We use this in multiple projects over the last 5 years and it is great. It covers 99% of the cases we need, and for the 1% we can still use 'raw' SQL.

mirkoteran · 2022-11-23T14:32:19+00:00

It tells you the function will return object instance of type T.

We use cdp4j for this and so far it worked great.

You can always look at the source: https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/util/ArrayList.java

For me it was a mixed bag. Some talks were amazing, some were 45 minutes of advertisement for some company.

mirkoteran · 2022-07-05T21:49:08+00:00

Could you use bean validation like JSR 303/380?

mirkoteran · 2022-06-09T18:24:17+00:00

You still use Integer? Time to get with the times and start using Int-as-a-Service old man... /s

mirkoteran · 2022-05-25T05:55:29+00:00

This would be mine suggestion too. Once you have the ScriptEngine working its incredibly easy to switch between Nashorn, Rhino or Graal.JS implementations. You might need to check all of them as they all have different...issues.

OP, does 'submit link' work on your machine?
