### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-devlake/issues?q=is%3Aissue) and found no similar feature requirement. ### Description Pull requests issued by automated robots do not indicate real development activity and distort the metrics. Therefore they should be removed. [CNCF/devstats](https://github.com/cncf/devstats) uses pattern-matching to detect bots. We can shamelessly snatch their pattern-list (see [here](https://github.com/cncf/devstats/blob/master/util_sql/exclude_bots.sql)) and use it in something like: ```sql select * from pull_requests where select * from pull_requests where -- not the full list but covers 99+% of the cases author_name not rlike '^robot-|-robot$|\\[bot\\]|-bot$|-ci$|-testing$' ``` If performance becomes an issue, then a table of robot IDs can be prepared beforehand and then joined with the target table. ### Use case How many PRs are attributable to bots? Apply the filter above to get some results. - For [clickhouse](https://github.com/ClickHouse/ClickHouse), bot activity is rampant: |created_year|PRs|bots contribution| |------------|---|----| |2020|7161|36.7%| |2021|11015|53.3%| |2022|4019|19.4%| - Overall ([oss.demo](https://grafana-oss.demo.devlake.io), 346 repos), not so much, but still significant, and rising: |created_year|PRs |bots contribution | |------------|------|------| 2020 |218558|4.0%| 2021 |215863|6.2%| 2022 |116016|7.7%| ### Related issues _No response_ ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
