If you don't want to specify a time period, remove "current_date-1".Ĭalculate the total sum of data scanned from S3 to Redshift Spectrum since the day before. Note: You can also use the CREATE TABLE query to calculate and store the data in another table. SELECT starttime::date as date, xid, query, trim(usename) as user,ĬASE WHEN s3_scanned_bytes 1 AND x_aborted=0 Here's an example: CREATE VIEW spectrum_cost AS Therefore, it's a best practice to calculate the daily query charges and to store it in another table, retaining a record of transferred bytes. There are no charges for failed or aborted queries.Īdditionally, system log tables (STL) retain only two to five days of log history, depending on log usage and available disk space. Note: All queries that scan up to 9.9 MB are rounded up and charged for 10 MB. In this example, the charges in Redshift Spectrum are queried against your S3 bucket for data scanned from the previous day. You can also use the following SQL query to calculate the Redshift Spectrum usage charges: SELECT To calculate the usage cost of Redshift Spectrum, multiply it by the cost per terabyte: $5 * 0.5657= $2.83 In this example, your usage is approximately 0.5657 terabytes. If the sum for s3_scanned_bytes returns 621,900,000,000 bytes when querying SVL_S3QUERY_SUMMARY, you have 0.565614755032584 terabytes (when you convert from bytes to terabytes). Virginia) Region, Redshift Spectrum charges $5 per terabyte. If you run this query against an S3 bucket in the US East (N. The following example shows you how to calculate the sum of all bytes for queries that started running since the previous day: SELECT sum(s3_scanned_bytes) ![]() You can also determine the sum of bytes for all queries from Redshift Spectrum in a specific time interval. ![]() To determine the sum of all bytes scanned from S3, use the following query: SELECT sum(s3_scanned_bytes) You can run the query against SVL_S3QUERY_SUMMARY to determine the number of bytes transferred by queryID: SELECT s3_scanned_bytes The s3_scanned_bytes column returns the number of bytes scanned from S3 sent to the Redshift Spectrum layer. To calculate the estimated query cost (and to obtain a summary of all S3 queries that were run in Redshift Spectrum), use the SVL_S3QUERY_SUMMARY table. Note: There are no charges for Data Definition Language (DDL) statements like CREATE, ALTER, or DROP TABLE statements for managing partitions and failed queries. For more information, see Amazon Redshift pricing. Byte numbers are always rounded up to the next megabyte, with a minimum of 10 MB per query. ![]() Additional charges (of $5 to $6.25 per TB of data scanned) can be incurred depending on the Region. You are charged for the number of bytes scanned from S3. With Redshift Spectrum, you can run SQL queries directly against the data in S3.
