Join us as we dig into ClickHouse sharding and replication, showing how they enable clusters that deliver fast queries over petabytes of data. We start with basic definitions of each, then move to practical issues. This includes the setup of shards and replicas, defining schema, choosing sharding keys, loading data, and writing distributed queries. We finish with tips on performance optimization.

love the blog about clickhouse stuff, this all info about sharding is going to help me a lot in the inevitable migration we are gonna do, no one knows much beside querying clickhouse here. you people's love toward sharing information related to clickhouse is kind of peculiar but welcome regardless, almost none of the channels/blogs have this much information on clickhouse, also what are you guys thoughts on clickhouse keeper, its a new(at least new to me) alternative to zookeeper which is not written in java.
