Transforms:

transform can be as part of a /histogram query whereby certain results are modified mid-query in order to see 'what could be' as a result. transform works by adding the following parameters to the histogram query:

• transformConditions=<filter>:<filterOps> details the conditions to look for before applying a transformation.
• transformFields=<field> details which field you wish to transform; for example, replFactor or numReplicas or diskspaceConsumed.
• transformOutputs=<output> details which numerical value you wish to use in-place of the live in-memory value for the transform field.

You can always find the full list of available finds by going to /transforms REST endpoint.

For example: * /histogram?set=files&type=fileReplica&sum=diskspaceConsumed&transformConditions=fileReplica:notEq:2&transformFields=fileReplica&transformOutputs=2 will output a histogram as if all files had replication factor 2.
