That's really a good news !
It would be great if we could release deployment recommendations (For example,
which scenarios are appropriate for the cluster version, how many nodes can
manage how much metadata and data, how to plan the cluster size by estimating
the amount of users' data, etc)
That sounds like a nice feature.
By the way, if my region is migrating or not ready, can I see its status?
As you said, can I see which regions are moving when my datanode has changed or
in rebalanced? For example, Region a is moving from node A to node B?
BR,
nchronously, so we can ensure that
the data files are logically consistent at this point" ? why? because of the
raft protocol?

about if the DBA just wants to restart one node..
However, the default behavior can be discussed: flush on one node by default or
on the whole cluster by default.

Sorry, I don't understand what the purpose and use of flushing current datanode
is.
IMO, flush all should mean that all storage group could be flushed, in another
word, flush sg is a subset of flush all.
For users, distributed is a black box, while SG is an exposed structure.
Therefore, for

Hi all,
When I was developing the snapshot interface for the configNode module, I
noticed that the parameters received by the serialization interface were all
defined as ByteBuffer, which seemed to have some problems. For example, the
external main process has no way of knowing how big the

Hi all,
We have submitted a formal PR based on the RocksDB metadata storage scheme.
This solution is used to solve the problem of too many time series, resulting
in insufficient memory, frequent full GC, and service unavailability.
Parts of the interface are still a work in progress, and we'd
Hi all,
After a node in the cluster went offline and then rejoined the cluster, I found
that my cluster was in a crash state.
Therefore, I did some check and analysis, there are some problems in the
SnapshotCatcup module.
Relevant descriptions are recorded here:
Hi，+1
In addition, can we add the version number or release information in our
documents?
Sometimes it's hard to figure out which version of the code a design document
in wiki corresponds to.
(the document may be too new, maybe it's stale)
Thanks
