Data Replication

Replication is the practice of sharing information to ensure consistency between redundant resources to improve reliability, fault-tolerance, or accessibility.

Replication

Types of Replication​

  • Single-Leader (Active/Passive): One node accepts writes, others copy.
  • Multi-Leader (Active/Active): Multiple nodes accept writes.
  • Leaderless: Any replica can accept writes (e.g., Cassandra, DynamoDB).
