After we refresh it, it will showing the data:
Can someone please help on this?
p
@Chintan Patel Are you using ClickHouse queries in dashboards? Once you start seeing that data - does it get into
No Data
state again?
a
@Chintan Patel what is the shardCount and replicaCount of clickhouse you are using?
replicaCount
has to be 1.
v0.12.0
only supports multiple shards and not multiple replicas of clickhouse. The data disappearing issue could be due to multiple replicas if configured
c
Yes @Ankit Nayan - We have made 2 replicas of ClickHouse.
We made replica count to 1 and it is working fine.
But question is there, let's say somehow of one of the shard is crashed then how we can recover that shard data @Ankit Nayan?
a
@Chintan Patel replicas is the answer for that unless you backup clickhouse data. We shall be releasing support for replication soon
c
okay thanks for the information @Ankit Nayan
