Amit Jain commented on OAK-4712:
--------------------------------

* The blob id returned from the node can be an in-memory blob (i.e. inlined in 
the id itself) and the threshold is governed by the property 
{{DataStore#getMinRecordLength()}}. So, {{InMemoryRecord.#isInstance()}} should 
be used to identify and filter them out. Otherwise, it the DataStore would 
return false negatives.

> This feature is to publish statistics about the S3DataStore via a JMX MBean.  
> There are two statistics suggested:
> * Indicate the number of files actively being synchronized from the local 
> cache into S3
> * Given a path to a local file, indicate whether synchronization of file into 
> S3 has completed
