Description:
This property specifies the replication of cuboids and metadata. The property value could be changed at any time.
Values and behavior:
Local: Cuboids are replicated at Query Engines' local cache path.
None: Cuboids are not replicated at Query Engines' and NFS's local cache path.
NFS: Cuboids and metadata are replicated at the NFS cache path, which is shared across all the Query Engines and BI Servers.
Default Value:
Local
Related Property:
Semantic Model: kyvos.query.dfs.read: Values of both kyvos.query.dfs.read and kyvos.cuboid.replication.type must not be None.
Scope:
Connection: If the property is set at the connection, then the property will override the application-level property value and will be applicable for all the semantic models.
Semantic model: If the property is set on a semantic model, then the value will override the connection level value for that semantic model.
Comes into effect:
The property comes into effect on the next iteration of the purge thread.
Recommendation:
In systems that have available space on a local disk, local replication is recommended. This prevents the need to pull from DFS, which saves disk transfer time.
