crdt

James Long's dotJS 2019 talk on how CRDTs enable local-first apps and how simple they can be to implement. He shows how to use them to build robust offline-capable frontends.

Martin Kleppmann's QCon London 2018 talk on keeping data consistent in distributed systems without a central leader. It surveys CRDT algorithms for syncing devices and collaborative editing over peer-to-peer networks.

Martin Kleppmann surveys current research on CRDTs, the algorithms for merging concurrent edits across offline replicas. He covers the hard parts such as rich text, moves and merge results that are technically correct but poor.

Martin Kleppmann's GOTO Berlin 2016 talk on how collaborative editors, offline apps, and multi-datacenter databases handle concurrent updates. It covers conflict resolution approaches including operational transformation and CRDTs, with a worked look at text CRDTs.

Daniel Azuma's ElixirConf 2018 talk on whether Docker and OTP conflict. He shows they can coexist and uses Horde and DeltaCrdt, with a live tank-game demo, to keep state alive across container kills.

A joint Erlang Factory 2016 keynote by Phoenix creator Chris McCord and Elm creator Evan Czaplicki on using the two together, including Phoenix.Presence design and PubSub optimizations.

Martin Kleppmann's Local-First Conf talk reviewing where the local-first idea came from, where it stands five years after the essay, and what the community should work toward. He argues for generic sync infrastructure.

Neil Fraser of Google presents Differential Synchronization, the algorithm behind MobWrite, for keeping multiple copies of a document in sync in real time. The talk argues the approach is robust, convergent and efficient.

A Linear engineer talks about scaling the company's sync engine, which keeps client data local and synchronized. It follows an earlier talk on the same system.
