Quick Start
This section describes how to run YCSB on Elasticsearch 5.x running locally.
1. Install and Start Elasticsearch
[Download and install Elasticsearch][1]. When starting Elasticsearch, you should [configure][2] 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)
