Apache Hive Flashcards
In one sentence, what is HIVE?
A system for managing and querying structured data built on top of Hadoop (HDFS)
Which technology does Hive rely on, and how?
Hive relies on MapReduce as its underlying processing engine. When executing queries, Hive translates them into a series of MapReduce jobs, leveraging the parallel processing capabilities of MapReduce to handle large-scale data processing tasks.
How do you use Hive to retrieve data?
It allows for a typical SQL interface to a distributed file structure
What other than a DFS can you use Hive on?
A CSV file
How does Hive compare to a regular SQL DB?
Hive and traditional SQL databases differ in their design and use cases. While a regular SQL database is typically optimized for online transaction processing (OLTP) with low-latency queries, Hive is designed for online analytical processing (OLAP) and is well-suited for handling large-scale data warehousing and analysis.
