YCSB/elasticsearch5/README.md

Quick Start

This section describes how to run YCSB on Elasticsearch 5.x running locally.

1. Install and Start Elasticsearch

Download and install Elasticsearch. When starting Elasticsearch, you should configure the cluster name to be es.ycsb.cluster (see below).

2. Set Up YCSB

Clone the YCSB git repository and compile:

git clone git://github.com/brianfrankcooper/YCSB.git
cd YCSB
mvn clean package

3. Run YCSB

Now you are ready to run! First, load the data:

./bin/ycsb load elasticsearch5 -s -P workloads/workloada

Then, run the workload:

./bin/ycsb run elasticsearch5 -s -P workloads/workloada

The Elasticsearch 5 binding requires a standalone instance of Elasticsearch. You must specify a hosts list for the transport client to connect to via -p es.hosts.list=<hostname1:port1>,...,<hostnamen:portn>:

./bin/ycsb run elasticsearch5 -s -P workloads/workloada \
-p es.hosts.list=<hostname1:port1>,...,<hostnamen:portn>`

Note that es.hosts.list defaults to localhost:9300. For further configuration see below:

Defaults Configuration

The default setting for the Elasticsearch node that is created is as follows:

es.setting.cluster.name=es.ycsb.cluster
es.index.key=es.ycsb
es.number_of_shards=1
es.number_of_replicas=0
es.new_index=false
es.hosts.list=localhost:9300

Custom Configuration

If you wish to customize the settings used to create the Elasticsearch node you can created a new property file that contains your desired Elasticsearch node settings and pass it in via the parameter to 'bin/ycsb' script. Note that the default properties will be kept if you don't explicitly overwrite them.

Assuming that we have a properties file named "myproperties.data" that contains custom Elasticsearch node configuration you can execute the following to pass it into the Elasticsearch client:

./bin/ycsb run elasticsearch5 -P workloads/workloada -P myproperties.data -s

If you wish to change the default index name you can set the following property:

es.index.key=my_index_key

By default this will use localhost:9300 as a seed node to discover the cluster. You can also specify

es.hosts.list=(\w+:\d+)+

(a comma-separated list of host/port pairs) to change this.

Configuring the transport client

The elasticsearch5 binding starts a transport client to connect to Elasticsearch using the transport protocol. You can pass arbitrary settings to this instance by using properties with the prefix es.setting. followed by any valid Elasticsearch setting. For example, assuming that you started your Elasticsearch node with the cluster name my-elasticsearch-cluster, you would need to configure the transport client to use the same cluster name via

./bin/ycsb run elasticsearch5 -P <workload> \
-p es.setting.cluster.name=my-elasticsearch-cluster

Using the Elasticsearch low-level REST client

The Elasticsearch 5 bindings also ship with an implementation that uses the low-level Elasticsearch REST client. The name of this binding is elasticsearch-rest. For example:

./bin/ycsb load elasticsearch5-rest -P workloads/workloada

You can configure the hosts to connect to via the same es.hosts.list property used to configure the transport client in the elasticsearch5 binding (note that by default you should use port 9200)
