Postgresql 如何使用TimescaleDB修复timeseries？

我有这样的数据：

Month_event | No_people | Cost
2017-03-01  | 78        | 120000 
2017-01-01  | 67        | 220000 
2017-07-01  | 121       | 320000 
2017-04-01  | 70        | 100000 

我通常在代码中使用Postgresql中的SQL查询（带窗口）来添加timeseries中缺少的值（复制上个月的值）：

这是我通常的疑问：

WITH 
calendar AS (
    SELECT interval_date::date FROM generate_series('2005-01-01'::date, (select release_month from mtd), '1 month'::interval) interval_date
),
m AS (
    SELECT *, LEAD(monthly_event) OVER (ORDER BY monthly_event) AS next_date
    FROM my_data
)
SELECT *
FROM calendar c
JOIN m
    ON c.interval_date BETWEEN m.monthly_date AND
    (CASE WHEN m.next_date IS NULL THEN date_trunc('month', current_date) ELSE m.next_date - '1 month'::interval END);

作为Postgres的扩展，我可以在TimescaleDB上重用相同的查询。

我想知道是否有更好的TimescaleDB解决方案，因为我无法从文档中找到它。

TimescaleDB 1.2中有一些新的功能，请参阅：间隙填充功能应该可以更轻松地完成您想要的任务

听起来像是想让我看看，但听起来像是我需要的，谢谢。完全错过了文档。不知道是否有任何关于TimescaleDB+GPU的计划

WITH 
calendar AS (
    SELECT interval_date::date FROM generate_series('2005-01-01'::date, (select release_month from mtd), '1 month'::interval) interval_date
),
m AS (
    SELECT *, LEAD(monthly_event) OVER (ORDER BY monthly_event) AS next_date
    FROM my_data
)
SELECT *
FROM calendar c
JOIN m
    ON c.interval_date BETWEEN m.monthly_date AND
    (CASE WHEN m.next_date IS NULL THEN date_trunc('month', current_date) ELSE m.next_date - '1 month'::interval END);
