Benchmarking Redis Map and INCR Operations with FunTester

Map Test

Idea

Design a simple scenario where a key‑value pair is stored in a Redis hash (map), verified for correctness, and then deleted. The case serves as an illustrative example rather than a specific production use case.

Test case

import com.funtester.base.constaint.FixedThread
import com.funtester.base.constaint.ThreadBase
import com.funtester.config.Constant
import com.funtester.db.redis.RedisBase
import com.funtester.frame.execute.Concurrent
import com.funtester.utils.StringUtil
import java.util.concurrent.atomic.AtomicInteger
/**
 * FunTester testing framework, Redis benchmark, map
 */
class RedisList05 extends RedisBase {
    static AtomicInteger num = new AtomicInteger(0)
    static RedisBase drive
    public static void main(String[] args) {
        String host = "FunTester"
        int port = 6379
        drive = new RedisBase(host, port)
        drive.index = 2
        int times = 200
        int thread = 10
        Constant.RUNUP_TIME = 0
        def tester = new FunTester(times)
        def task = new Concurrent(tester, thread, "redis测试实践之map")
        task.start()
        drive.close()
    }
    private static class FunTester extends FixedThread {
        String key = DEFAULT_STRING + num.getAndIncrement()
        FunTester(int limit) {
            super(null, limit, true)
        }
        @Override
        protected void doing() throws Exception {
            def k = "f" + getNanoMark()
            def v = StringUtil.getString(10000)
            drive.hset(key, k, v)
            def hget = drive.hget(key, k)
            if (v != hget) fail()
            drive.hdel(key, k)
        }
        @Override
        ThreadBase clone() {
            return new FunTester(this.limit)
        }
    }
}

Test result

Detailed performance numbers and charts are omitted for brevity.

INCR Test

Idea

Multiple threads concurrently increment a single Redis key using the INCR command to verify thread‑safety; a second variant with both increment and decrement is mentioned but not demonstrated.

Test case

import com.funtester.base.constaint.FixedThread
import com.funtester.base.constaint.ThreadBase
import com.funtester.config.Constant
import com.funtester.db.redis.RedisBase
import com.funtester.frame.execute.Concurrent
import java.util.concurrent.atomic.AtomicInteger
/**
 * FunTester testing framework, Redis benchmark, incr
 */
class RedisList06 extends RedisBase {
    static AtomicInteger num = new AtomicInteger(0)
    static RedisBase drive
    public static void main(String[] args) {
        String host = "FunTester"
        int port = 6379
        drive = new RedisBase(host, port)
        drive.index = 2
        int times = 200
        int thread = 20
        Constant.RUNUP_TIME = 0
        def tester = new FunTester(times)
        def task = new Concurrent(tester, thread, "redis测试实践之INCR")
        task.start()
        drive.close()
    }
    private static class FunTester extends FixedThread {
        String listName = DEFAULT_STRING + num.getAndIncrement()
        FunTester(int limit) {
            super(null, limit, true)
        }
        @Override
        protected void doing() throws Exception {
            drive.incr("FunTester1123")
        }
        @Override
        ThreadBase clone() {
            return new FunTester(this.limit)
        }
    }
}

Test result

Detailed performance numbers and charts are omitted for brevity.

Conclusion

The FunTester framework series for Redis performance testing is now complete; the next planned series will apply the framework to MySQL benchmarking.
