Hive on ACID - Alan Gates, Hortonworks
Apache Hive provides SQL access for data in Hadoop. Traditionally data in Hadoop is write once read many. But with traditional data
warehousing use cases moving to Hadoop there is a need to support transactional update and delete of records. Hive has recently implemented
ACID compliant row level insert, update, and delete as well as very low latency ingestion of streaming data from tools like Storm and Flume. This is done with snapshot isolation between queries. This talk will cover the intended use cases, architectural challenges of implementing updates and deletes in a write-once file system, and details of changes to the file storage formats and transaction management system.
