A method can include caching, at a first computing node and a second computing node, a replica of an anchor object. The anchor object can link to a topology object storing elements comprising a distributed data storage system. The first computing node can reside in a first availability zone. The second computing node can reside in a second availability zone. The first availability zone and the second availability zone can be part of a data center. The first computing node and the second computing node can each store a data partition associated with a data container belonging to a tenant. A replica of the topology object can be cached at the first availability zone and the second availability zone. A query requiring data associated with the tenant can be executed based on the cached replica of the anchor objects and/or topology objects.
