### Steps to execute the benchmark
|
|
|
|
1. Build `client-benchmark-noop-api-plugin` with `./gradlew :client:client-benchmark-noop-api-plugin:assemble`
|
|
2. Install it on the target host with `bin/elasticsearch-plugin install file:///full/path/to/client-benchmark-noop-api-plugin.zip`.
|
|
3. Start Elasticsearch on the target host (ideally *not* on the machine
|
|
that runs the benchmarks)
|
|
4. Run the benchmark with
|
|
```
|
|
./gradlew -p client/benchmark run --args ' params go here'
|
|
```
|
|
|
|
Everything in the `'` gets sent on the command line to JMH. The leading ` `
|
|
inside the `'`s is important. Without it parameters are sometimes sent to
|
|
gradle.
|
|
|
|
See below for some example invocations.
|
|
|
|
### Example benchmark
|
|
|
|
In general, you should define a few GC-related settings `-Xms8192M -Xmx8192M -XX:+UseConcMarkSweepGC -verbose:gc -XX:+PrintGCDetails` and keep an eye on GC activity. You can also define `-XX:+PrintCompilation` to see JIT activity.
|
|
|
|
#### Bulk indexing
|
|
|
|
Download benchmark data from http://benchmarks.elasticsearch.org.s3.amazonaws.com/corpora/geonames and decompress them.
|
|
|
|
Example invocation:
|
|
|
|
```
|
|
wget http://benchmarks.elasticsearch.org.s3.amazonaws.com/corpora/geonames/documents-2.json.bz2
|
|
bzip2 -d documents-2.json.bz2
|
|
mv documents-2.json client/benchmark/build
|
|
gradlew -p client/benchmark run --args ' rest bulk localhost build/documents-2.json geonames type 8647880 5000'
|
|
```
|
|
|
|
The parameters are all in the `'`s and are in order:
|
|
|
|
* Client type: Use either "rest" or "transport"
|
|
* Benchmark type: Use either "bulk" or "search"
|
|
* Benchmark target host IP (the host where Elasticsearch is running)
|
|
* full path to the file that should be bulk indexed
|
|
* name of the index
|
|
* name of the (sole) type in the index
|
|
* number of documents in the file
|
|
* bulk size
|
|
|
|
|
|
#### Search
|
|
|
|
Example invocation:
|
|
|
|
```
|
|
./gradlew -p client/benchmark run --args ' rest search localhost geonames {"query":{"match_phrase":{"name":"Sankt Georgen"}}} 500,1000,1100,1200'
|
|
```
|
|
|
|
The parameters are in order:
|
|
|
|
* Client type: Use either "rest" or "transport"
|
|
* Benchmark type: Use either "bulk" or "search"
|
|
* Benchmark target host IP (the host where Elasticsearch is running)
|
|
* name of the index
|
|
* a search request body (remember to escape double quotes). The `TransportClientBenchmark` uses `QueryBuilders.wrapperQuery()` internally which automatically adds a root key `query`, so it must not be present in the command line parameter.
|
|
* A comma-separated list of target throughput rates
