Impala vs SQLite: What are the differences?
Impala: Real-time Query for Hadoop. Impala is a modern, open source, MPP SQL query engine for Apache Hadoop. Impala is shipped by Cloudera, MapR, and Amazon. With Impala, you can query data, whether stored in HDFS or Apache HBase – including SELECT, JOIN, and aggregate functions – in real time; SQLite: A software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. SQLite is an embedded SQL database engine. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite reads and writes directly to ordinary disk files. A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file.
Impala and SQLite are primarily classified as "Big Data" and "Databases" tools respectively.
"Super fast" is the primary reason why developers consider Impala over the competitors, whereas "Lightweight" was stated as the key factor in picking SQLite.
Impala is an open source tool with 2.18K GitHub stars and 824 GitHub forks. Here's a link to Impala's open source repository on GitHub.
According to the StackShare community, SQLite has a broader approval, being mentioned in 314 company stacks & 477 developers stacks; compared to Impala, which is listed in 15 company stacks and 5 developer stacks.
