JMeter Couchbase Sampler

Introduction

This plugin adds feature to JMeter to load test couchbase (no sql database) using couchbase sdk client library.

Download the source code from the Gitlab.
Just do a mvn clean install (Git bash is required)
Jar will be generated under the target directory (jmeter-couchbase-sampler-x.jar).
Copy the Jar to <Jmeter Installed Directory>/lib/ext/

Add Config element -> Couchbase Config
Provide the connection string details (couchbase capella/on-premise hostname, credentials, bucket, scope, collection and other connection options required)
Provide a name in "Bucket Object" field to export the connecting object to sampler element.
To establish connection with multiple bucket, add more than one config element with different object name.
Add Sampler -> Couchbase sampler element in Thread Group
provide the Exported object name in the step 3 and select the query type (N1QL/Data operations)
provide scope/collection information - if required
Use the query field to perform the Data Operations/Query Operations using N1QL

Data operations enables the simplest way to retrieve or mutate data where the key is known.
It covers CRUD operations, document expiration, and optimistic locking with CAS
The supported CRUD operations were INSERT, GET, UPSERT, REMOVE
Default timeout is set to 5 minutes for any CRUD operations
The parameter field is ignored when the query type is not N1QL

The SQL++ mode is considered to write formal SQL queries on couchbase
The query is always performed at the Cluster level, using the query method
The scope and collection parameters were ignored when the query type is selected as N1QL
Default query timeout is set to 5 minutes.
