IMPALA-12965: Add debug query option RUNTIME_FILTER_IDS_TO_SKIP

Runtime filter still have negative effect on certain scenario such as
long wait time that delays scan and cascading runtime filter chain that
prevents parallel execution of fragments. Having debug query option to
simply skip a runtime filter id from being scheduled can help us
investigate and test a solution early before implementing the
improvement code.

This patch add RUNTIME_FILTER_IDS_TO_SKIP option to do that. This patch
also improve parsing of multi-value query options to not split at ','
char that is within two double quotes and ignore empty/whitespace value
if exist.

Testing:
- Add BE test in query-options-test.cc
- Add FE test in runtime-filter-query-options.test

Welcome to Impala

Lightning-fast, distributed SQL queries for petabytes of data stored in open data and table formats.

Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:

More about Impala

The fastest way to try out Impala is a quickstart Docker container. You can try out running queries and processing data sets in Impala on a single machine without installing dependencies. It can automatically load test data sets into Apache Kudu and Apache Parquet formats and you can start playing around with Apache Impala SQL within minutes.

To learn more about Impala as a user or administrator, or to try Impala, please visit the Impala homepage. Detailed documentation for administrators and users is available at Apache Impala documentation.

If you are interested in contributing to Impala as a developer, or learning more about Impala's internals and architecture, visit the Impala wiki.

Supported Platforms

Impala only supports Linux at the moment. Impala supports x86_64 and has experimental support for arm64 (as of Impala 4.0). Impala Requirements contains more detailed information on the minimum CPU requirements.

Supported OS Distributions

Impala runs on Linux systems only. The supported distros are

  • Ubuntu 16.04/18.04
  • CentOS/RHEL 7/8

Other systems, e.g. SLES12, may also be supported but are not tested by the community.

Export Control Notice

This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.

Build Instructions

See Impala's developer documentation to get started.

Detailed build notes has some detailed information on the project layout and build.
