You can group the time column into 5 second intervals and count the rows using the following query in Presto:

1
2
3
4
5
6
SELECT 
  COUNT(*) as rows_count,
  DATE_TRUNC('5 second', time_column) as time_interval
FROM your_table
GROUP BY DATE_TRUNC('5 second', time_column)
ORDER BY time_interval;


In this query:

  1. Replace "your_table" with the name of your table.
  2. Replace "time_column" with the name of your time column.
  3. The DATE_TRUNC function is used to truncate the time column into 5 second intervals.
  4. The GROUP BY clause groups the data by the truncated time intervals.
  5. The COUNT(*) function is used to count the number of rows in each interval.
  6. The results are ordered by the time intervals.


This query will give you the count of rows in 5-second intervals based on the time column in your table.
