| Adds 'Trino' provider (with lower memory footprint for tests) (#15187) While checking the test status of various CI tests we came to conclusion that Presto integration took a lot of memory (~1GB) and was the main source of failures during integration tests, especially with MySQL8. The attempt to fine-tune the memory used turned out in the discovery, that Presto DB stopped publishing their Docker image (prestosql/presto) - apparently after the aftermath of splitting-off Trino from Presto. Th split-off was already discussed in #14281 and it was planned to add support for Trino (which is the more community-driven fork of the Presto - Presto remained at Facebook Governance, where Trino is an effort continued by the original creators. You can read more about it in the announcement: https://trino.io/blog/2020/12/27/announcing-trino.html. While Presto continues their way under The Linux Foundation, Trino lives its own live and keeps on maintaining all artifacts and libraries (including the image). That allowed us to update our tests and decrease the memory footprint by around 400MB. This commit: * adds the new Trino provider * removes presto integration and replaces it with trino * the trino integartion image is built with 400MB less memory requirementes and published as apache/airflow:trino-* * moves the integration tests from Presto to Trino Fixes: #14281 | 5 年前 |
