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 Analytical 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.
