Thread Pools

Thread pools on the JVM should usually be divided into the following three categories:

1. CPU-bound
2. Blocking IO
3. Non-blocking IO polling

Each of these categories has a different optimal configuration and usage pattern.

Object Query Language (OQL)

$ java -version
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)

OQL is SQL-like query language to query Java heap. OQL allows to filter/select information wanted from Java heap. While pre-defined queries such as "show all instances of class X" are already supported by HAT, OQL adds more flexibility. OQL is based on JavaScript expression language.

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

  def create[F[_]](
    queue: Queue[F, Option[Either[Throwable, String]]],
    destinationFile: String
  )(implicit blocker: Blocker,
    F: Concurrent[F],
    cs: ContextShift[F]): F[WriteToFile[F]] = {

    def toFile(fileName: String): Pipe[F, String, Unit] =
      _.through(text.utf8Encode)

// this flavour is pure magic...
def toDouble: (Any) => Double = { case i: Int => i case f: Float => f case d: Double => d }
  
// whilst this flavour is longer but you are in full control...
object any2Double extends Function[Any,Double] {
  def apply(any: Any): Double = 
    any match { case i: Int => i case f: Float => f case d: Double => d }
}

// like when you can invoke any2Double from another similar conversion...
