Lease Pattern in .NET: A Lock With an Expiration Date That Saves Your Data

Read Original

This technical article details the lease pattern in .NET, a distributed locking mechanism with an expiration date. It contrasts indefinite locks with leases, which use a TTL to allow system recovery after crashes or network issues. The post covers core semantics, design choices like TTL selection and renew cadence, and provides a production-oriented implementation guide using Redis for atomic acquire and renew operations.
