The CouchDB driver for SBK supports single/multiple Writer , single/multiple reader performance benchmarking.
To make simple demo/test, you can run the local CouchDB server docker image as follows:
docker run -p 5984:5984 -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=admin -d couchdb
make sure you have redirected the port 5984 from docker to local system
Now, you can run the CouchDB writer benchmarking as follows.
kmg@kmg:~/kmg-linux/SBK$ ./build/install/sbk/bin/sbk -class couchdb -size 100 -writers 1 -seconds 60
