> To improve performance of S3, it is recommended to use object keys which enables to save
data in multiple partitions. [1]
> The current key format dataStore_SHA1_HASH put all data in single partition. It is recommended
to remove dataStore_ prefix and split SHA1_HASH to enable randomness in prefix. 
> for e.g. if older key format is dataStore_004cb70c8f87d78f04da41e7547cb434094089ea. change
this key format to 004c-b70c8f87d78f04da41e7547cb434094089ea
> *Also consider upgrade scenario to migrate older key format data
