 # Surreal Crawler
 
-Mapping with a budget of 1000 (crawl 1000 sites, so many more links are actually discovered), on [my webiste](https://oliveratkinson.net) on 8/26/2024 took 1m9s.
+Crawls sites saving all the found links to a surrealdb database. It then proceeds to take batches of 100 uncrawled links untill the crawl budget is reached. It saves the data of each site in a minio database.
 
-This is including the crawl and loading into the database and linking sites. (Locally hosted surreal db instance)
+### TODO
 
-This run created 4299 site links with 23286 links between the sites. (It found my this git site which really bolsters those numbers.)
+- [ ] Domain filtering - prevent the crawler from going on alternate versions of wikipedia.
+- [ ] Conditionally save content - based on filename or file contents
+- [x] GUI / TUI ? - Graphana
+- [x] Better asynchronous getting of the sites. Currently it all happens serially.
+- [ ] Allow for storing asynchronously
 
-## Install / Build
+3/17/25: Took >1hr to crawl 100 pages
 
-* You will need rust to compile the crawler [rustup.rs](https://rustup.rs)
-* You need python3 (will come installed on most linux distros) and poetry for dependancy management.
-    * Install `pipx`, `python3`
-    * Then: `pipx install poetry`
-    * Then: `poetry install` to install the project dependancies
-* You need to install [surrealdb](https://surrealdb.com)
+3/19/25: Took 20min to crawl 1000 pages
+This ment we stored 1000 pages, 142,997 urls, and 1,425,798 links between the two.
 
-## Use
+3/20/25: Took 5min to crawl 1000 pages
 
-Just run `./crawl.sh {url}` and it will start crawling. You can tweak the budget inside [crawl.sh](https://git.oliveratkinson.net/Oliver/internet_mapper/src/branch/main/crawl.sh) if you want.
+3/21/25: Took 3min to crawl 1000 pages
 
-You can also prefix the command with `time` to benchmark the system, such as: `time ./crawl.sh https://discord.com`.
