What exactly is Archiver (Archiving large_file) doing?

[the_wolverine]

In splunkd.log we see:

01-31-2019 12:38:03.683 -0800 INFO Archiver - Archiving large_file=/opt/splunk/etc/apps/search/lookups/large_lookup.csv of size_in_bytes=262621937 (exceeding threshold=52428800)

This is actually useful for finding out how large lookup files are. What is Splunk actually doing with it?

HI @the_wolverine

The archiver process goes through your search head knowledge objects (such as lookups) and bundles them into a tar file so they can be sent to the indexers. Its good to keep your bundle size small as possible so this is ujst an informational message to say there is a large file. If it is not needed then you should delete it or add it to the replicationBlacklist of distsearch.conf

Cheers

This is simply informing you that the lookup is larger than the max 50mb individual file size in a knowledge bundle
