为了在Elaticache Redis集群目标上应用插入、更新和删除操作，需要配置AWS DMS任务并使用AWS Lambda转换。首先，需要在AWS Lambda上创建一个函数，该函数将AWS DMS任务的变更数据修改为带有有效信息的特定Redis命令。然后，将创建的Lambda函数与DMS任务关联。以下是代码示例:

exports.handler = function(event, context) {
    event.records.forEach(function(record) {
        if (record.eventName == "INSERT") {
            // Convert INSERT change data to Redis command
            var redisCommand = "SET " + record.dynamodb.NewImage.key.S + " " + record.dynamodb.NewImage.value.S;
            // Output Redis command to DMS
            console.log(redisCommand);
        }
        else if (record.eventName == "MODIFY") {
            // Convert MODIFY change data to Redis command
            var redisCommand = "SET " + record.dynamodb.NewImage.key.S + " " + record.dynamodb.NewImage.value.S;
            // Output Redis command to DMS
            console.log(redisCommand);
        }
        else if (record.eventName == "REMOVE") {
            // Convert REMOVE change data to Redis command
            var redisCommand = "DEL " + record.dynamodb.Keys.key.S;
            // Output Redis command to DMS
            console.log(redisCommand);
        }
    });
};

在配置DMS任务时，关联上述Lambda函数即可。这样，DMS就能在Elasticache Redis集群目标上应用插入、更新和删除操作。
