Kotlin + JOOQ + Intellij 15 = SLOOOOW!

Support

Everything works fine, but JOOQ relative auto compilation and code analysis are painfully slow.

import org.jooq.DSLContext

object MainKotlin {
    lateinit var context: DSLContext

    @JvmStatic
    fun main(args: Array<String>) {
        context.select().from // <-- From here Intellij will not respond.
    }
}

import org.jooq.DSLContext;

public class MainJava {
    public static void main(String[] args) {
        DSLContext context = null;
        context.select().from // <- Works like Intellij.
    }
}

Here is a test project - GitHub - sungmin-park/kotlin-jooq-test: Kotlin + JOOQ + Intellij 15 = SLOOOW

Any ideas?

I downloaded the project and tried the code completion. It’s really slow at that location. It takes many seconds for the completion list to show up. But if I wait until that and try it again it becomes rather quick here and in all other points where I tried that. Do you experience the same or do you have slow completion all the time?

import org.jooq.DSLContext
import org.jooq.impl.DSL

object MainKotlin {
    lateinit var context: DSLContext

    @JvmStatic
    fun main(args: Array<String>) {
        context.select(DSL.value(1)).from(DSL.dual()).orderBy(DSL.rand()).limit(10, 100).fetch { it.value1() } // Evaluate code caches.

        context.select(DSL.value(1)). // still slow.
    }
}

Sadly slow almost all the time.

Actually, slow code completion is not the major issue. I can handle that. Major problem is slow code analysis.

I have the exact same issue. This is bad enough to make jooq nearly unusable with Kotlin/IntelliJ.

Hello JetBrains folks, Lukas from the jOOQ team here.

I’m happy to help with the resolution of this issue, if I can. jOOQ makes heavy use of overloading + generics + varargs, which can be a bit of a challenge for type inference algorithms that aren’t implemented optimally (or if the type inference spec is too lenient).

Let me know if I can be of any assistance.

Did you add an issue to youtrack.jetbrains.com? That is the best place to report bugs, performance related or otherwise.

We are working on it.
You can try out dev version where some major performance issues has been fixed.
