## What it is
X-Pipe is Ctrip's Redis multi-datacenter replication management system built on Redis's master-slave replication protocol. It provides low-latency cross-datacenter (including cross-public-network) replication, one-click datacenter failover, replication monitoring, and alerting.

## Use cases
- replicate redis across multiple datacenters
- redis disaster recovery with datacenter failover
- sync redis data over the public internet between sites
- reduce redis master full sync load from remote slaves
- one-click redis datacenter switchover
- monitor redis replication lag and get alerts

## When to choose
- you run Redis in multiple datacenters and need DR or local reads
- you need cross-datacenter replication over public networks with buffered logs to survive network outages
- you want managed, monitored datacenter switchover with rollback support

## When to avoid
- you only run Redis in a single datacenter
- you need Redis Cluster's native multi-master or sharding features rather than async replication
- you cannot operate additional Java services (Console, Keeper, MetaServer) alongside Redis

## Facets
- artifact type: service
- maturity: active
- function: monitoring, alerting, caching, deployment, microservices
- domain: databases, microservices, infrastructure-as-code, self-hosted
- platform: jvm, self-hosted
- tags: redis, cross-datacenter, disaster-recovery, psync2, keeper, multi-dc-replication, dr-switching, replication, devops, docker, linux, web-server
