Design Assumptions:
|
|
1. the number of directories are magnitudely smaller than the number of files
|
|
2. unlimited number of files under any directories
|
|
Phylosophy:
|
|
metadata for directories and files should be separated
|
|
Design:
|
|
Store directories in normal map
|
|
all of directories hopefully all be in memory
|
|
efficient to move/rename/list_directories
|
|
Log directory changes to append only log file
|
|
Store files in sorted string table in <dir_id/filename> format
|
|
efficient to list_files, just simple iterator
|
|
efficient to locate files, binary search
|
|
|
|
Testing:
|
|
1. starting server, "weed server -filer=true"
|
|
2. posting files to different folders
