| # Reddit Subreddits25 Archive |
|
|
| This repository contains a compressed Reddit archive organized by subreddit and record type. |
| It was prepared from a local bundle named `reddit_torrent_download_bundle`; that bundle did |
| not include provenance or licensing documentation, so users must independently verify that |
| their use complies with applicable terms, licenses, privacy requirements, and laws. |
|
|
| ## Contents |
|
|
| - Files: 79,955 (39,974 comment shards and 39,981 submission shards) |
| - Compressed size: 3,965,777,405,390 bytes (approximately 3.97 TB) |
| - Encoding: newline-delimited JSON compressed with Zstandard |
| - Layout: `data/<comments|submissions>/<sha256-prefix>/<subreddit>_<type>.jsonl.zst` |
|
|
| The two-character hash directory is derived from the original filename and only exists to |
| keep repository directories small. `manifest.tsv` records every remote path, compressed size, |
| and original filename. |
|
|
| ## Reading a shard |
|
|
| ```bash |
| zstd -dc data/comments/00/example_comments.jsonl.zst | python -m json.tool --json-lines |
| ``` |
|
|
| In Python, use the `zstandard` package and parse one line at a time; shards can be very large. |
| Schema and field availability vary across Reddit eras and between comments and submissions. |
|
|
| ## Safety and privacy |
|
|
| This historical archive can include deleted, offensive, explicit, or personally identifying |
| content. Do not treat continued presence in the archive as consent for reuse. Apply appropriate |
| filtering and governance before training models, redistributing excerpts, or exposing records. |
