Yes, I looked into ozone. Couldn't tell how what the operational overhead is.
Thanks as always! ________________________________ From: Tsz Wo Sze <[email protected]> Sent: Monday, March 7, 2022 5:51:09 AM To: [email protected] <[email protected]> Subject: Re: Change group id Hi Asad, Your application may consider managing a different ID, says dbID. The dbID normally maps to a Ratis groupID. Whenever a rename of the groupID is needed, we may map that groupID to a different dbID. BTW, Apache Ozone may suit your use case well. It is a distributed object store, which maintains multiple containers. Each container uses a Ratis group when it is being built. It supports creating multiple containers on the same set of nodes.

(As part of that group ids may move around in unexpected ways) Then more servers to scale out with their own group ids. The ingress protion then maps client requests key ranges to group ids and forwards it to the right place? Bigger picture: What I am trying to figure out is can I build a datastore that can be "easily" dynamically resized as the volume of data grows. ________________________________ From: Tsz Wo Sze <[email protected]<mailto:[email protected]>> Sent: Sunday, March 6, 2022 3:28:29 AM To: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> Subject: Re: Change group id Hi Asad, Currently, we do not support changing group id. What is your use case?

Will it create a new blank state machine to replicate? Or it will be able to still work on existing data?
