Query select usesysid as user_id, usename as username, usecreatedb as db_create, usesuper as is_superuser, valuntil as password_expiration from pg_user order by user_id This would have been a lot easier if all different sources of access to Redshift had used a dedicated user. Create New Schema After using FlyData to load data into Amazon Redshift, you may want to extract data from your Redshift tables to Amazon S3. It stores and process data on several compute nodes. 100. The b… You can query these More details on the access types and how to grant them in this AWS documentation. In addition to the tables that you create, your database contains a number of system Amazon Redshift enforces a quota of the number of tables per cluster by node type, including user-defined temporary tables and temporary tables created by Amazon Redshift during query processing or system maintenance. You can further summarize/pivot the above results to show e.g how many times a table was accessed by certain user on certain day? For maintenance operations, Amazon Redshift reduces the amount of compute resources required by operating only on frequently accessed tables and portions within those tables. RedShift unload function will help us to export/unload the data from the tables to S3 directly. Query below returns list of users in current database. The stl_ prefix denotes system table logs. Create: Allows users to create objects within a schema using CREATEstatement Table level permissions 1. Schema level permissions 1. Snapshot tables have an STV prefix. Usage: Allows users to access objects in the schema. These system tables contain information about your installation and about There are three main variations on the Redshift Create table command. Essentially I enriched the data from STL_SCAN by joining: The reason DISTINCT is used when selecting from STL_SCAN is because it displays info on slice and query step level. A linked table will enable you to read from and write data to the Orders table. enabled. Query below lists databases on Amazon Redshift instance. This is because Redshift is based off Postgres, so that little prefix is a throwback to Redshift’s Postgres origins. Amazon Redshift documentation is quite good. Double-click the linked table … so we can do more of it. There isn’t an existing system table or view that gives you all of the information mentioned above. CREATE TABLE table_name ( column_name1 data_type1, column_name2 data_typ2 ) CREATE TABLE AS Join thousands of aspiring developers and DevOps enthusiasts Take a look, https://docs.aws.amazon.com/redshift/latest/dg/c_intro_STL_tables.html, Terraform Tutorials: Frequently Asked Questions, Terraform Tooling for Small and Medium Businesses. Kubernetes vs Docker Swarm. A dates table like that works very well for reports. administrative and maintenance tasks. The query tables that are visible only to superusers. Amazon Redshift retains a great deal of metadata about the various databases within a cluster and finding a list of tables is no exception to this rule. The result will look something like this: Javascript is disabled or is unavailable in your Query select oid as database_id, datname as database_name, datallowconn as allow_connect from pg_database order by oid; Columns. This job will restore the selected tables to the existing cluster. If you've got a moment, please tell us what we did right as a superuser to You can do it via checking last modification time of table's file. You can access these logs using SQL queries against system tables, or choose to save the logs to a secure location in Amazon S3. Other things you might want to add: public holiday flag, last day of quarter flag, last day of year flag (handy for reports grouped by last date of the period).
