Summary: Introduce concepts in the query plan and execution
Key: IMPALA-13070
URL: https://issues.apache.org/jira/browse/IMPALA-13070
Project: IMPALA
Issue Type: Documentation
Reporter: Quanlong Huang
We currently have 3 sections for "Impala Concepts":
* Components of the Impala Server
* Developing Impala Applications
* How Impala Fits Into the Hadoop Ecosystem
[https://impala.apache.org/docs/build/asf-site-html/topics/impala_concepts.html]
It'd be helpful to introduce concepts used in the query plan and query
execution, e.g.
* Coordinator & Executor
* Fragment & Fragment Instance
* Operator, Pipeline
* Cardinality, Memory Reservation, Memory Estimate
* Split/ScanRange
* Runtime Filter
* Query Profile
