Waltz: A Distributed Write-Ahead Log

We are happy to announce the open source release of Waltz. Waltz is a distributed write-ahead log. It was initially designed to be the ledger of money transactions on the WePay system and was generalized for broader use cases of distributed systems that require serializable consistency. Waltz is similar to existing log systems like Kafka in that it accepts/persists/propagates transaction data prod

“Waltz is what we describe as a write-ahead log. This recorded log is neither the output of a change-data-capture from a database nor a secondary output from an application. It is the primary information of the system state transition. ”

Kafka に楽観的ロックによる整合性保証を組み合わせた分散 WAL。WAL をどう分散するのかなと思ったら、1つのパーティションは1つのサーバーノードだけが管理する形式だった。Multi master みたいなのを期待してたけども
