Introduction
  Who is Nik
  What is elasticsearch
  My plan - 20 minutes of prepared material and then whatever folks would like
  Who are you people?
    Name, experience with Elasticsearch, what you are interested in doing


Fork the repo
Download latest JDK

Demonstration Part 1 - https://gist.github.com/nik9000/7f1c8670dd84a008c97035c1d40b2a16

git clone [email protected]:yourname/elasticsearch.git

Demonstration Part 2 - https://gist.github.com/nik9000/1500f8896b30db104ec0f113f85a627a

Ok! Now that you have it, lets run it!
  export JAVA_HOME=~/Downloads/tmp/jdk-15/
  ./gradlew run
  <wait a long time for it to compile, download, compile, download, compile, and start>
  new window. Now use the gists!

Where should we go from here? Ideas:
  Get it into an IDE
  Run tests
  Trace the execution on the _bulk request
  Trace the execution of an agg
  Run a test in your IDE
  Look for good first issues




Notes if we trace a _bulk request:
  Every API has three parts RestBulkAction/BulkRequest/BulkResponse/TransportBulkAction
  TransportBlahAction does the actual action.
  In this case it groups the parts of the bulk into BulkShardRequest per shard and then runs *that* it.
  *that* is serialized to the node holding the primary for the shard
  It performs on the primary and then serializes to the replicas and performs there
  The word "Transport" is because you might have been "transported" from one node to another and then executed. Its a weird name.
