 # SLURM Database Characterization
 
+## Data 
+
+I got a database dump as my input data. With some light research, it looks like it *is* technically possible to read this in directly to python and a pandas dataframe, but.... I don't want to do that, because it seems pretty hairy.
+
+So....
+
+First things first, I decided to convert it to CSV.
+
+Based on https://blog.twineworks.com/converting-a-mysql-dump-to-csv-files-b5e92d7cc5dd
+
+I used 
+
+```
+cat slurmdb_backup_20190417_031528 | dos2unix | gawk -f split.awk 
+```
+
+where split.awk is from https://gist.github.com/slawo-ch/894349427655d22398f825dc535a40f0#file-split-awk
+
+and slurmdb_backup_20190417_031528 is the unzipped database dump.
+
+The output of the conversion spits out files which look something like the below
+
