A technical guide on choosing between ETS and Mnesia for Erlang state management, comparing performance, durability, and distribution with a hybrid implementation example.
Seamless In‑Place OTP Application Upgrade with release_handler
Upgrade a running Erlang OTP node to a newer release without downtime using release_handler. Follow the step‑by‑step guide to prepare, execute, verify, and roll back if needed.
When to Use one_for_one vs one_for_all in Erlang Supervisors
Match Erlang OTP restart strategies to your failure domain so a crashing worker does not restart unrelated services.

Erlang's async message passing relies on per-process mailboxes managed by the BEAM VM. Understand selective receive, unbounded mailbox risks, and practical diagnostics.
Erlang OTP Supervisor Crash Loops: Diagnosis and Recovery Guide
A practical diagnostic guide for Erlang OTP supervisor crash loops: recognize the restart intensity pattern, map symptoms to causes, run ordered checks, apply fixes tied to findings, and know when escalation is correct.
Performing a Zero‑Downtime Hot Code Upgrade in Erlang/OTP with Release Handler
Learn how to update an Erlang/OTP application on a live node using release_handler, appup files, and OTP’s built‑in rollback. Follow a step‑by‑step guide, verify the upgrade, and recover if something goes wrong.
Choosing Erlang’s one_for_one Supervision Strategy for Fault‑Tolerant Services
Learn how the one_for_one restart strategy isolates failures in Erlang OTP supervision trees, see a concrete gen_server example, and understand when to use it.
