Evaluating pending object replication rules

A computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to perform an operation comprising:

• receiving, at a first node of a plurality of nodes, a first replication rule, wherein the first replication rule defines object replication among the plurality of nodes;
• labeling the first replication rule as pending, wherein a second replication rule on the first node is labeled as active;
• upon receiving a request to predict an effect of the first replication rule, identifying, based on the first replication rule, a first object of a plurality of objects;
• and
• upon determining that the first object is present on the first node but is not present on a second node of the plurality of nodes, outputting an indication of the first object.

A system comprising:

• one or more computer processors;
• and
• a memory containing a program which when executed by the one or more computer processors performs an operation, the operation comprising:
• receiving, at a first node of a plurality of nodes, a first replication rule, wherein the first replication rule defines object replication among the plurality of nodes;
• labeling the first replication rule as pending, wherein a second replication rule on the first node is labeled as active;
• upon receiving a request to predict an effect of the first replication rule, identifying, based on the first replication rule, a first object of a plurality of objects;
• and
• upon determining that the first object is present on the first node but is not present on a second node of the plurality of nodes, outputting an indication of the first object.
