Gold Query

WITH w2022 AS (
SELECT json_extract(repo, '$.id') AS repo_id, COUNT(*) AS cnt_2022
FROM YEAR_2022
WHERE type = 'PushEvent'
GROUP BY repo_id
),

FROM YEAR_2023
WHERE type = 'PushEvent'
GROUP BY repo_id

FROM w2022
JOIN w2023 ON w2022.repo_id = w2023.repo_id
WHERE w2023.cnt_2023 - w2022.cnt_2022 >= :push_threshold
