Which statement about .tsidx files is accurate?

BSplunk removes outdated .tsidx files every 5 minutes.

CSplunk updates .tsidx files every 30 minutes.

DEach bucket in each index may contain only one .tsidx file.

Show Suggested Answer

Suggested Answer: A

A .tsidx (time-series index) file in Splunk consists of two main components:

Lexicon : A dictionary of unique terms (e.g., field names and values) extracted from indexed data.

Posting List : A mapping of terms in the lexicon to the locations (offsets) of events containing those terms.

Here's why this works:

Purpose of .tsidx Files : These files enable fast searching by indexing terms and their locations in the raw data. They are critical for efficient search performance.

Structure : The lexicon ensures that each term is stored only once, while the posting list links terms to their occurrences in events.

Other options explained:

Option B : Incorrect because Splunk does not remove .tsidx files every 5 minutes. These files are part of the index and persist until the associated data is aged out or manually deleted.

Option C : Incorrect because .tsidx files are updated as data is indexed, not at fixed intervals like every 30 minutes.

Option D : Incorrect because each bucket can contain multiple .tsidx files, depending on the volume of indexed data.

Not sure about that, I thought each bucket could have multiple .tsidx files.

I’m pretty certain that each index can have multiple .tsidx files, so option D seems off to me.

I feel like I read that Splunk cleans up .tsidx files regularly, but I can't recall if it was every 5 minutes or something else.
