Hi Abhishek, While the server does conceptually have to check the settings for the log level and trace events, it is able to do this very efficiently, so I would not worry about that from a performance standpoint; MarkLogic keeps a view of the configuration in memory and can access that information very quickly.
Now if you are logging millions of entries, that can take some resources, as it does have to be written to the ErrorLog.txt file, but again, I think you would have to be logging a lot of messages to make an appreciable difference in a query. As far as a performance comparison, as with all things, I'd recommend you profile it. I would expect them to be about the same, and for their cost to be very small (again, unless you call them a lot of times). -Danny From: [email protected] [mailto:[email protected]] On Behalf Of Abhishek53 S Sent: Wednesday, June 29, 2011 2:41 AM To: General MarkLogic Developer Discussion Cc: [email protected] Subject: [MarkLogic Dev General] xdmp:trace and xdmp:log Hi Folks Now this question is more theoretical. xdmap:trace and xdmp:log both are used to log information into ErrorText.txt file. The point of confusion is related to the mechanism both API uses for logging. Say if I use multiple time xdmp:log and xdmp:trace in the query , For every time logging API is used in the same query Do i check for the server settings for the corresponding logging API. Trying to explain through example Query: xdmp:log(<some-info>)....xdmp:log(<some-info>).....xdmp:log(<some-info>)....xdmp:log(<some-info>)..xdmp:trace(<some-info>) (Query is using multiple times logging throug xdmp:log & xdmp:trace) For each time xdmp:log do it verify server settings for level (info,debug...) For each time xdmp:trace do it verify server settings for event ID (event id is active/present) What about performance comparison between both the APIs? Thanks in advance !
