Resharding a CH cluster with a S3 storage

[kilic.a...@gmail.com]

Hi folks,

We are investigating a DataLake solution using ClickHouse with our data stored in S3.

We're wondering what does it requires when we want to reshard our cluster by scaling from 2 to 3 nodes for example.

Is it something that handle by ClickHouse himself or it requires a specific action in our side to tell where the parts are located after the resharding?

Best regards,

Alifirat Kilic.
