> Only zookeeper based state store allows all records to be inserted even 
> though only few of them already exists and "errorIfExists" is true, however 
> file/fs as well as mysql based putAll fails the whole putAll operation 
> immediately after encountering single record that already exists in the 
> records and "errorIfExists" is provided true (which is the case while 
> inserting records for the first time).
> For all implementations, we should allow inserts of the records that do not 
> already exist and report any record as failure that already exists, rather 
> than failing the whole operation and not trying to insert valid records.
