## Summary
- Introduces a new `application-logs` core module with a driver pattern
(disabled/console/clickhouse) to capture and persist logic function
execution logs
- Adds a ClickHouse `applicationLog` table with per-line log storage,
30-day TTL, and `ORDER BY (workspaceId, timestamp, applicationId,
logicFunctionId)`
- Surfaces application logs in the existing frontend audit logs table as
a new "Application Logs" source with dedicated columns (Function,
Timestamp, Level, Message, Execution ID)
## Details
**Write path**: `LogicFunctionExecutorService.handleExecutionResult()`
parses the multi-line log string from driver output into individual `{
timestamp, level, message }` entries, generates an execution UUID, and
passes them to `ApplicationLogsService.writeLogs()` which delegates to
the configured driver.
**Driver pattern**: Follows the exception-handler module style (Symbol
injection token + `forRootAsync` dynamic module). Three drivers:
- `DISABLED` (default) — no-op, prevents information leaking
- `CONSOLE` — structured stdout logging with level-based `console.*`
calls
- `CLICKHOUSE` — inserts rows into the `applicationLog` ClickHouse table
**Read path**: Extends the existing event-logs module by adding
`APPLICATION_LOG` to the `EventLogTable` enum, table name mapping, and
normalization logic.
**Config**: New `APPLICATION_LOG_DRIVER_TYPE` environment variable
(default: `DISABLED`).

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
