IMPALA-12815: Support timestamp for scan predicates for external data source table. Binary SCAN predicates involving timestamp literals are pushed down to remote Database. The current logic assumes ISO 8601 (SQL standard) format for timestamp literals - 'yyyy-mm-dd hh:mm:ss.ms' Testing: - Added custom cluster tests for timestamp predicates with operators: '=', '>', '<', '>=', '<=', '!=', 'BETWEEN' for postgres, mysql and remote impala. - Added coverage for timestamp with/without time in the timestamp - Added coverage for timestamp with/without milliseconds in timestamp. - Added Planner tests to check predicate pushdown for date/timestamp literals, date/timestamp functions and CASTs Change-Id: If6ffe672b4027e2cee094cec4f99b9df9308e441 Reviewed-on: http://gerrit.cloudera.org:8080/21015 Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Reviewed-by: Wenzhe Zhou <wzhou@cloudera.com>
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:
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.

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.
Impala runs on Linux systems only. The supported distros are
Other systems, e.g. SLES12, may also be supported but are not tested by the community.
This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.
