What does "replication" mean in programming?
replication is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The process of copying data from one node to multiple others to ensure durability and availability. Synchronous replication waits for all replicas to confirm before acknowledging a write; asynchronous replication lets replicas catch up later.
Example
"PostgreSQL replication keeps a standby in sync — if the primary fails, the standby can take over immediately."
