 ### Memory usage
 
 DuckDB queries requiring `JOIN`, `GROUP` and `ORDER BY` operations are very memory intensive. Because of that, some steps are divided into chunks (groups) with a set number of rows per chunk.

 QuackOSM has been roughly tuned to different workloads. The `rows_per_bucket` variable is set based on an available memory in the system:
 
 | Memory     | Rows per group |

 ### Disk usage
 
 The algorithm depends on saving intermediate `.parquet` files between queries.
-As a rule of thumb, when parsing a full file without filtering, you should have at least 10x more free space on disk than the base file has (100MB pbf file -> 1GB free space to parse it).
