![]() It loads your schema at runtime, creating an object instance that allows you to query tables, views, functions, and stored SQL files as if. The goal of Massive is to make it easier for you to use PostgreSQL's amazing features, not to hide them under a load of abstraction. Once selected, every execution using the same session, will add a new column with performance results for that execution.ģ milliseconds to execute from SET STATISTICS TIME ON and 5 milliseconds Client processing time from the Client Statistics Tab. Massive is a PostgreSQL-specific data access tool. If omitted, the value returned by the last step will be used as the final value. a function returning the result of the aggregate function given its final state. Will receive the value from init for the first step. I've often used it as a way to compare stored procedure performance executed with different parameters, especially useful when changing those parameters affects the volume of data processed and returned. a function receiving the current state and a value to aggregate and returning a new state. The client versus how much time was spent waiting for the server. based on what I think it should be named but it returned no results. The time statistics tells you how much time was spent processing on The workload consists of 43 queries and can test the efficiency of full scan and. The network statistics lets you see how much traffic is moving from Use custom titles for tabs with results You can define a tab title in the comment section before the query. I want to test the impact of the change I am proposing on execution time. Based on the parameter sometimes it returns 3 rows and sometimes it returns over 5K rows. Select the Open results in new tab checkbox and click OK. I am testing the performance a query and trying to fix a parameter sniffing issue. In the IDE settings Ctrl+Alt+S, go to Database Query Execution. Number of rows affected or returned, and the number of transactions An easy psql solution would be to reinject the :ROWCOUNT psql variable immediately after the query into another query to return the 'No value exists' text when :ROWCOUNT is zero. You can change this behavior and create a tab each time you run a new query. That can be when tuning a complex stored procedure. Of INSERT, DELETE, UPDATE, and SELECT statements – think of how useful In a test query, you specify: The query you’re testing The faked inputs, each labeled with their referenced name The expected output of running the query on the faked inputs Behind the scenes, when you run the test, we dynamically replace the inputs to the dataset query with your faked input data. Some really valuable information can be found here, such as the number You can use SET STATISTICS TIME ON to get the exact amount of time the server spends executing the query.Īnd Client Statistics can help determine the amount of time the client spends consuming it.
