And then further down:
> ClickHouse Keeper is a drop-in replacement for ZooKeeper
That opening was about ClickHouse in general, but the article is about one particular application using the database.
- tylerhannan 3y agoYep. Generally, ClickHouse Keeper provides the coordination system for data replication and distributed DDL query execution for ClickHouse clusters.
- dathinab 3y agodrop in replacement doesn't change anything about my question, interfaces are not all what matters and now knowing more about it I would say the answer to my question is a clear yes, it used ZK for something ZK wasn't at all intended for which means it makes a lot of sense that they replace it
- macksd 3y agoAre you perhaps confusing ClickHouse, with ClickHouse Keeper (one of ClickHouse's components?) Sounds to me like ClickHouse is the database, and ClickHouse Keeper is the ZK drop-in replacement. A bit like HBase being a database, and ZooKeeper being a service it is heavily dependent on.
- dathinab 3y agoyes and no yes I confused the quotes but the question in general about weather ClickHouse Keeper and ZooKeeper are designed for completely different use-cases which happen to be similar and can work with the same interface still stands and by now knowing more then my original comment I would answer the question with yes
