We can use the Redshift percentile_cont function to do that: select. An inverse distribution function where, for each row, PERCENTILE_DISC returns the value that To order the final result , use the SQL ORDER BY clause set. PERCENTILE_CONT computes the percentile by first computing the row number where the To order the final result , use the SQL ORDER BY clause set.

Using SQL may be the wrong tool for the job if the number of data points is very large. I need to find the 75th, 90th, 95th, and 98th percentile as well as the percentrank of <=5 seconds, 10 seconds, 30 seconds and 60 seconds. Any help is appreciated!

percentile value cannot be achieved in one step in this procedure. The user will have to first calculate the 99th percentile value, subset the data and then apply 90th percentile, making it inefficient while handling big data with minimal transfer.

For example Transaction summary Transaction Name Response Time Transact_1_login 8 Transact_1_login 7 Transact_1_login 5 Transact_1_login 2 Transact_1_Search 1 Transact_1_Search 2 Transact_1_Search 3 Transact_1_Search 4 For example, PERCENTILE_DISC (0.5) will compute the 50th percentile (that is, the median) of an expression. PERCENTILE_DISC calculates the percentile based on a discrete distribution of the column values.
