When libs/core was created, several classes were moved from server's o.e.common package, but they were not moved to a new package. Split packages need to go away long term, so that Elasticsearch can even think about modularization. This commit moves all the classes under o.e.common in core to o.e.core. relates #73784 |

Steps to execute the benchmark
- Build
client-benchmark-noop-api-pluginwith./gradlew :client:client-benchmark-noop-api-plugin:assemble - Install it on the target host with
bin/elasticsearch-plugin install file:///full/path/to/client-benchmark-noop-api-plugin.zip. - Start Elasticsearch on the target host (ideally not on the machine that runs the benchmarks)
- 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: Always "rest"
- 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).
- A comma-separated list of target throughput rates
