A brief history of Hive, in which we look at the evolution of Hive from the original command line application to today’s cloud-based and hybrid (on-prem + cloud) solution. We also look briefly at the future, touching on some important innovations and future directions. We then show in more detail what technological solution Hive uses to ensure that the data stored in the tables can be modified (UPDATE / DELETE) even if the storage medium (HDFS, S3) does not allow it.
