Repeat the preceding steps to create five ECSs named Cassandra-1 (192.168.0.15), Cassandra-2 (192.168.0.240), Cassandra-3 (192.168.0.153), Cassandra-4 (192.168.0.175) and ycsb-Cassandra (192.168.0.60).
Migration Performance Reference Environment: Pika (single node) and pika-port are deployed on an ECS with 8 vCPUs and 32 GB memory on Huawei Cloud. The target DB is a three-node GeminiDB Redis instance with 8 vCPUs and 16 GB memory.
If the password contains at signs (@),exclamation marks (!), or percent signs (%), replace them with hexadecimal URL codes %40, %21, and %25 respectively. For example, if the password is ****@%***!
Figure 16 Verifying the creation results Insert data into the table, for example, INSERT INTO nosql_table (user_id, age, user_name) VALUES (1, 10, 'user1'); INSERT INTO nosql_table (user_id, age, user_name) VALUES (2, 20, 'user2'); INSERT INTO nosql_table (user_id, age, user_name)

): operations executed by a database per second Test Model No.: indicates the test model sequence number.
Do not delete too much data (tens or hundreds of thousands of elements) of the LIST and ZSET types via a single batch deletion command (for example, LREM, LTRIM, and ZREMRANGEBYSCORE). Deleting a large amount of data may take a long time, affecting other commands.

Once a partition becomes extremely large, access to the partition increases load of a server where the partition is located, and even causes the Out of Memory (OOM) error. HotKey issue: This issue occurs when a key is frequently operated in a short period of time.
