I don't recommend using this backend for writing for two reasons: + +1. Since sqlite is a relational database, not a hash-table, fetching each +reference takes O(logn) time (with indices). This might hurt compared to a +hash-table O(1) in cases where there's millions of blocks. + +2. Unless your filesystem sucks at handling lots of small files, there is little +benefit over the simple file-based backend. This might be a major motivation for +using this backend in FAT32 (65536 max files in a directory ~ max 2GB of ERIS +data) or NTFS (lots of small files kill it). |
