As the database grows in size, so does the index management cost.

It’s really scary knowing that such corruptions are happening in the memory of our computers and servers – that is before they even reach the network and storage portions of the stack. That data must then be safely transported over a network to the storage system where it is written to disk. Well, if you’re using one of the storage protocols that lack end-to-end checksums (e.g. performance storage database checksum data corruption data safety

For some internal reasons well known Amazon S3 bucket was chosen for this purpose. The choice affected the project's unit test base.

However, Hive cannot access a single table directly using a single query with the data of this Hive table across different mediums of storage and different clusters. This becomes a need when the data volume grows too large to fit a single medium of storage or cluster, and also when the users need to take into account the following considerations: Storage cost, where some partitions are less important than others and can be stored on cheaper storage tiers.
