From Kvrocks to GeminiDB Redis API

Updated on 2025-01-03 GMT+08:00

Kvrocks is an open-source NoSQL key-value database that is compatible with the Redis ecosystem. It uses namespace to partition data based on the underlying RocksDB. However, it is relatively weak in cluster management. Kvrocks needs to cooperate with other components to create clusters and does not support some Redis commands, such as stream and hyperloglog that are frequently used in message flow and statistics scenarios.

GeminiDB Redis API is a cloud-native NoSQL database with decoupled compute and storage and full compatibility with Redis. To ensure data security and reliability, it provides multi-copy, strict consistency based on a shared storage pool. It provides high compatibility, cost-effectiveness, high reliability, elastic scalability, high availability, and hitless scale-out. GeminiDB Redis API functions as good as Redis Cluster does and is 100% compatible with native APIs. You can migrate your on-premises Redis databases to GeminiDB Redis ones without modifying any code. In addition to adapting to Kvrocks, GeminiDB Redis API also improves management capability and compatibility with Redis.

This section describes how to migrate data from Kvrocks to GeminiDB Redis API.

Migration Principles

The open-source tool kvrocks2redis is used to migrate data from Kvrocks to GeminiDB Redis API. At the code layer, Kvrocks namespace is adapted to the source GeminiDB Redis database.

The migration process consists of two phases: full migration and incremental migration. During full migration that is first performed, snapshots are created for Kvrocks and the corresponding data version (seq) is recorded. Then, the complete data files are parsed into Redis commands and written to GeminiDB Redis API. After the full migration is complete, the incremental migration starts. The migration tool cyclically sends PSYNC commands to Kvrocks and continuously forwards the obtained incremental data to GeminiDB Redis API.

Precautions

  • Kvrocks2redis needs to extract data from Kvrocks to local files, parse commands from the files, and send the commands to the target GeminiDB Redis instance. During this process, the performance of the source DB may be affected, but no data is compromised theoretically.
  • If a fault occurs when the migration tool is running, the migration tool automatically stops to facilitate fault locating.
  • For security purposes, GeminiDB Redis API does not provide database clearing commands. Ensure that no data exists in the database before the migration.

Prerequisites

  • Deploy the kvrocks2redis on an independent host.
  • Ensure that the source DB, target DB, and migration tool can communicate with each other.
  • Back up data of the source Kvrocks instance in advance.
  • Clear all data on the destination GeminiDB Redis instance.

Procedure

To migrate data from Kvrocks to GeminiDB Redis API, choose Service Tickets > Create Service Ticket in the upper right corner of the console and contact customer service.
