![]() Links to various reference documents, if applicable. Links to discussions on the devlist, if applicable. We should limit depth of statistics history and allow to enable/disable statistics gathering in runtime. Statistics gather could cause performance degradation and excessive memory consumption. Statistics kept on node locally, collected from other nodes only when needed. ![]() IO stats could be enabled/disabled for the given session through SQL commands, e.g. Through DBeaver > 6.2.Access to the query statistics should be provided through both JMX and system SQL view. For SQL views it could be very convenient to get specific information due to power of SQL, e.g.They should be grouped by SQL query and have at least min, max, avg time of execution min, max, avg of IO operations ( when IO stats are enabled) number of executions. For all executed queries we should gather statistics.Also we need to support query cancel for JDBC, ODBC and thin clients.Share Improve this answer Follow answered at 20:46 rogeriodsc 44 3 Add a comment 5 I'm not sure the accepted answer is correct. We propose MySQL-like syntax: KILL QUERY 4 Answers Sorted by: 2 With this option activated dbeaver it will show you a red marker on the line that contains the error.Postgres: SELECT pg_cancel_backend() and SELECT pg_terminate_backend().ORACLE: ALTER SYSTEM CANCEL SQL 'SID, SERIAL, SQL_ID'.Industrial RDBMS vendors (Oracle, Postgres, MySQL) have the following approaches to do it: User should be able to cancel any query by query id.This query id should be used for all of the query parts executed on other nodes. In such case management could be done on query level. As example: b3c0624a-122c-46ea-9d65-67b56df00001 and 341. 4 Answers Sorted by: 2 With this option activated dbeaver it will show you a red marker on the line that contains the error. But it wont help if socket timeout exception occurs. If you cant stop query then you may try to force disconnect (click on the connection in navigator tree and click disconnect in main toolbar or context menu). Each of execution query should have unique identifier for whole cluster. It could be an initial node UUID + sequentially growing number of an executing queries on the node. If yes you may try to stop/cancel current running query.Have ability to cancel of execution of a query from any node or client. ![]() User should be able to understand what is going on with executed queries: Many database vendors have some instruments for SQL management and monitoring.
