Answer / Rajnesh Kant Sagar
Apache Impala is designed to provide fast query performance over large data sets stored in Hadoop Distributed File System (HDFS) or Apache HBase. It achieves this by using a MPP (Massively Parallel Processing) architecture, which enables parallel processing of queries across multiple nodes. Additionally, Impala uses a compiled execution engine to minimize the overhead of query compilation, and it leverages local data processing where possible for improved performance.
