Aspect	Open Source	Enterprise
Governance	Maintainers, community consensus, meritocracy-based influence	Empowered teams, lightweight oversight, guardrails over gates
Code Review	Public PRs, async reviews from global contributors, emphasis on transparency	Small PRs, fast feedback loops, pair/mob programming as alternative
Documentation	README-driven, contributor guides essential, public wikis	Living documentation, lightweight ADRs, docs as code
Branching Strategy	Fork-and-PR model, contributors work in personal forks	Trunk-based development, short-lived feature branches (< 1 day)
Communication	Public channels (GitHub issues, Discord, mailing lists)	Co-located teams (in space /and or time), minimal ceremony
Release Cadence	Varies widely, often semver-based, maintainer-driven	Continuous delivery, deploy on merge, feature flags for controlled rollout
Testing	CI on PRs, community-contributed

Optimistic Locking assumes that a database transaction conflict is very rare to happen. It uses a version number of the record to track the changes. It raise an error when other user tries to update the record while it is lock.

usage

Just add a lock_version column to the table you want to place the lock and Rails will automatically check this column before updating the record.

Pessimistic locking assumes that database transaction conflict is very likely to happen. It locks the record until the transaction is done. If the record is currently lock and the other user make a transaction, that second transaction will wait until the lock in first transaction is release.
