> Due to MySQL's InnoDB limitation where index keys can be a maximum of 3072 bytes, the `cq_file_metrics.id` field, when using the `utf8mb4` character set, can only be set to `VARCHAR(767)` at its longest. To ensure SonarQube data can be collected correctly without hitting this field length limit, we may need to modify the format or handling of `cq_file_metrics.id`. This particular aspect of the issue will be tracked in a separate follow-up issue. Regarding the index key length limitation, we plan to address this for `cq_file_metrics.id` (which is derived from `_tool_sonarqube_file_metrics.file_metrics_key`) by **hashing the file path portion** of `_tool_sonarqube_file_metrics.file_metrics_key` to restrict its length. This approach will necessitate considering **data migration**. The simplest and most straightforward method would be to **clear the existing data** from both the `cq_file_metrics` and `_tool_sonarqube_file_metrics` tables. This way, subsequent data collection will use the new ID format, avoiding any conflicts between old and new data representations. -- This is an automated message from the Apache Git Service.
