Is there any way to fetch aerospike data with jmeter. i need to pass the key value from jmeter for which data value should be fetched from aerospike.
Given you have JDBC Driver for Aerospike NOSQL Database in JMeter Classpath you can use JDBC Connection Configuration to set up database URL and credentials and JDBC Request sampler to run your queries and store results into JMeter Variables
See The Real Secret to Building a Database Test Plan With JMeter for detailed instructions on setting up JMeter for database testing.
