Re: Do table statistics get replicated as part of hive BDR replication

Hi @Daggers ,

 

Based on the public doc here:

https://www.cloudera.com/documentation/enterprise/release-notes/topics/cm_rn_new_changed_features.ht...

 

It says:

Table and partition-level column statistics stored in the Hive metastore and used by Impala are now replicated during Hive Replication. This is supported between a replication source with Cloudera Manager running version 5.10 or higher and a replication target running Cloudera Manager 5.10 or higher. Because this change replicates more information, the same schedule may take more time to complete if column statistics are present.

 

Thanks and hope this helps.
