v.20.4Experimental Feature
Initial Support for ReplicatedMergeTree on S3
Initial support for ReplicatedMergeTree over S3 (it works in suboptimal way) #10126 (Pavel Kovalenko)
Why it matters
This feature allows users to leverage Amazon S3 for storing replicated data managed byReplicatedMergeTree tables. It provides an alternative to local storage, facilitating scalable and durable storage options in cloud environments, although the current implementation works in a suboptimal way and may have performance limitations.How to use it
To use this feature, configure aReplicatedMergeTree table with S3-compatible storage by specifying the appropriate S3 storage settings in the table configuration. Note that this functionality is in initial development stage, so users should expect experimental behavior.
