Checksums in Storage Systems and Why the Enterprise Should Care


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

Partitioned Hive Table Across Storage Systems Using Alluxio


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.
