Summary: Implement a C++/Rust native client
Key: IMPALA-15388
URL: https://issues.apache.org/jira/browse/IMPALA-15388
Project: IMPALA
Issue Type: Epic
Reporter: Abhishek Rawat
The existing Python-based {{impala-shell}} introduces significant client-side
latency through interpreter initialization, heavy module imports, and runtime
serialization. Because standard benchmarks measure end-to-end execution, this
overhead accumulates—particularly the high Python startup cost for
short-running queries and Thrift deserialization overhead for large result
sets. This artificially inflates latency metrics and obscures Impala’s true
backend performance.
Modern analytical engines provide compiled native clients to avoid these
interpreter penalties. This task tracks investigating and prototyping a
lightweight, natively compiled CLI client (e.g., C++ or Rust) to replace the
Python runtime, eliminate startup overhead, and provide accurate, unskewed
performance profiling for end-to-end workloads.
