I stored a .csv file of 19KB (1000 rows) into badgerDB. I’m also running another process along with badgerDB and after completing that process I receive this output from badgerDB:

Can someone help me understand what this output means?
Thank you.

It’s a summary of the level breakdown of the LSM tree. Google log structured merge tree or the leveldb architecture to learn more there.
