YCSB/elasticsearch

Quick Start

This section describes how to run YCSB on ElasticSearch running locally.

1. Set Up YCSB

Clone the YCSB git repository and compile:

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

2. Run YCSB

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

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

Then, run the workload:

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

For further configuration see below:

Defaults Configuration

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

cluster.name=es.ycsb.cluster
node.local=true
path.data=$TEMP_DIR/esdata
discovery.zen.ping.multicast.enabled=false
index.mapping._id.indexed=true
index.gateway.type=none
gateway.type=none
index.number_of_shards=1
index.number_of_replicas=0
es.index.key=es.ycsb

Custom Configuration

If you wish to customize the settings used to create the ElasticSerach 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 elasticsearch -P workloads/workloada -P myproperties.data -s

If you wish to use a in-memory store type rather than the default disk store add the following properties to your custom properties file. For a large number of insert operations insure that you have sufficient memory on your test system otherwise you will run out of memory.

index.store.type=memory
index.store.fs.memory.enabled=true
cache.memory.small_buffer_size=4mb
cache.memory.large_cache_size=1024mb

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

es.index.key=my_index_key
