Changelog Entry

Description

This PR will improve db performance, especisally sqlite, by:

Enable WAL for sqlite. It will only work for sqlite.
Reduce the update number of user.last_active_at to reduce write conflicts. It will improve performance for all db theoretically.

To avoid breaking changes, all the 2 improvements are disabled by default. User needs to enable them manually. I have enable both on my environment for 1 month, and they will improve performance significantly.

For more informantion, see discussion #15123.

Added

Add DATABASE_ENABLE_SQLITE_WAL option to enable SQLite WAL mode for better performance.
Introduce a new decorator deduplicate in backend/open_webui/utils/misc.py, which prevents a decorated function from being called repeatedly within a specified time interval with the same arguments; repeated calls within the interval will return None.
Add DATABASE_DEDUPLICATE_INTERVAL configuration to control the deduplication interval (unit: second) for updating user.last_active_at.

Breaking Changes

If DATABASE_ENABLE_SQLITE_WAL is enabled, it will enable WAL mode for sqlite (default: disabled).
If DATABASE_DEDUPLICATE_INTERVAL is not 0, user.last_active_at might not be accurate (default: 0).

Screenshots or Videos

Before the improvements (or DATABASE_ENABLE_SQLITE_WAL=false and DATABASE_DEDUPLICATE_INTERVAL=0)
Only enable WAL (DATABASE_ENABLE_SQLITE_WAL=true and DATABASE_DEDUPLICATE_INTERVAL=0)
Enable both (DATABASE_ENABLE_SQLITE_WAL=true and DATABASE_DEDUPLICATE_INTERVAL=10)

(In the second picture, there is no UPDATE operation since it's in 10s interval)
