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: ```auto Level 0 []: NumTables: 04. Size: 32 KiB of 0 B. Score: 0.00->0.00 StaleData: 0 B Target FileSize: 64 MiB Level 1 []: NumTables: 00. Size: 0 B of 10 MiB. Score: 0.00->0.00 StaleData: 0 B Target FileSize: 2.0 MiB Level 2 []: NumTables: 00.

Score: 0.00->0.00 StaleData: 0 B Target FileSize: 2.0 MiB Level Done ``` 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.
