Checksums in Storage Systems and Why the Enterprise Should Care

DZone

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

DZone

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.

Four Different Ways to Write in Alluxio

DZone

We refer to external storage such as HDFS or S3 as under storage. Alluxio is a new layer on top of under storage systems that can not only improve raw I/O performance but also enables applications flexible options to read, write and manage files. Given an application such as a Spark job that saves its output to an external storage service; Writing the job output to the memory layer in a colocated Alluxio worker will achieve the best write performance.
