Skip to main contentStorage
OpenKol stores normalized posts and analysis snapshots in Postgres. This is the source of truth for permalinks, history, and KOL profiles.
Caching
Redis is used to cache:
- Post details and normalized metadata
- Analysis snapshots for fast page loads
- Token pair and liquidity details
- Candle data for common windows
Local history
The client keeps a lightweight analysis history in LocalStorage. This allows quick reopen of recent analyses without extra requests.
Why it matters
Persistent storage provides auditability, and caching keeps the analysis experience fast while reducing repeated external calls.
