 # Metadata Database for Danbooru2023
+
 Danbooru 2023 datasets: https://huggingface.co/datasets/nyanko7/danbooru2023
 
 The latest entry of this database is id 7,866,491. Which is newer than nyanko7's dataset.

+## Format
+
+This dataset contains 3 format but they store same contents:
+
+* Sqlite (.db)
+  * have 2 versions: with/without index.
+* Parquet
+  * Parquet files' name indicate the sqlite/duckdb table name.
+  * It is recommended to use post.parquet when you need to export tons of content.
+* Duckdb (.duckdb)
+  * Although duckdb support index, provided duckdb file doesn't have index in it.
+
+`others` folder will contains some pre-exported files like tags for each post.
 
 ## Details
+
 This section contains some details that you need to be aware of if you want to use other ORM system or use plain SQL query to utilize this database.
 
 #### Custom Enum Fields
+
 Some fields in Post/Tags use my custom enum field to store type/category or something like that:
 
 * Post.rating

 The con of this design is the database file will be 1.5x larger than before(we have 0.25B entries for the post-tag pairs), but the query speed become 2~3x faster, so I think it is acceptable.
 
 After done some checking, I can ensure that all the "categorical tag list" can be done by full list + filter, and that is how I done it now. Check the db.py for more details.

 #### Utils
+
 if you think above details are too complicated, just use the db_utils.py and other PeeWee API to utilize this database.
 I also provide a write_csv.py for exporting whole dataset into csv for data analysis.
