/tmp filling up about commoncrawl-fetcher-lite HOT 5 CLOSED

I had been meaning to do this. The challenge was that there was a single fetcher for the index fetcher and the file extractor. I've broken this out into the fetcher which pulls the literal bytes out of the WARC and the indexFetcher which grabs the index files. This means that you can now read index files from your local file system but still extract from the WARCs via s3 or https.

I've documented how to do this in https://github.com/tballison/commoncrawl-fetcher-lite/blob/main/AdvancedScenarios.md

I also fully bolded the point about having to download 300GB of index files for each month's run!

Outstanding! Thanks, I will recompile after my current run is done. This will also help me identify new formats to create signatures for in PRONOM.

Would it make sense to be able to limit the number of index files downloaded? 300GB is a lot of data. Perhaps a setting that works like maxFilesExtracted to limit index files, maxIndexFilesDownloaded.

That way a user could use the local index files for repeat extractions of files without pulling down the whole 300GB.

Also, in the event of a crash, does restarting the process skip already downloaded index files?
