These build tools are also used by the `elasticsearch-hadoop` project maintained by elastic.

### `build-tools-internal`

This project contains all elasticsearch project specific build logic that is not meant to be shared
with other internal or external projects.

## Build guidelines

This is an intentionally small set of guidelines to build users and authors
to ensure we keep the build consistent. We also publish elasticsearch build logic

The microbenchmark suite is also handy for ad-hoc microbenchmarks but please remove them again before merging your PR.

## Getting Started

Just run `gradlew -p benchmarks run` from the project root
directory. It will build all microbenchmarks, execute them and print
the result.

## Running Microbenchmarks

	// metacacheBlockSize is the number of file/directory entries to have in each block.
	metacacheBlockSize = 5000

	// metacacheSharePrefix controls whether prefixes on dirty paths are always shared.
	// This will make `test/a` and `test/b` share listings if they are concurrent.
	// Enabling this will make cache sharing more likely and cause less IO,
	// but may cause additional latency to some calls.

#### Http2Connection

This lock guards internal state of each connection. This lock is never held for blocking operations. That means that we acquire the lock, read or write a few fields and release the lock. No I/O and no application-layer callbacks.
