Splunk table dedup8/6/2023 ![]() I wouldn't worry about the number of records scanned, if they both got identical results, but I'd make sure the time frames and output results were identical before assuming the code was working apples-to-apples. Check the results against each other and make sure they came out identical. I am trying to create a table in Splunk that contains several fields that were extracted plus a count of the total number entries that get returned when I give Splunk a string to search for. (50k?)įootnote 2 - use at the end of your earliest and latest to make sure the two timelines are exactly the same. It is a transforming command which has a natural limit on how many results it will allow. Here's the basic syntax: 1 dedup fieldname This will remove all duplicate rows from the table, keeping only the first occurrence of each duplicate row based on the values in the fieldname field. Then do whatever makes sense.įootnote: Be careful of table. To remove duplicates from a Splunk table, you can use the dedup command. For overall throughput, slightly more CPU time but all of it on the indexers is far better than slightly less CPU time all on the search head. ![]() They are close enough in overall performance that you can go either way and no one will say "Boo" bout it.Ĭheck the details of the run and see how much of that time is on the indexers and how much on the search head. Your_search_criteria |eval xmessagePayload = messagePayload | spath input=xmessagePayload output=xorderID path=ord:AddOrderV2.ord:order.So, given your results, it looks like the results are in alignment with my expectations - dedup is slightly less efficient, as expected, but only slightly so.
