LCORE-1062: Updated connectors description#907
Conversation
WalkthroughAdds expanded docstrings to quota limiter and DB connection modules; additionally, UserQuotaLimiter.init now invokes self.connect() to initialize its database connection and tables during instantiation. No other signature or behavioral changes reported. Changes

13-25: Fix return type annotation to match docstring and satisfy type checking.The function's return type is annotated as
Any(line 12), but the docstring correctly documents it returnssqlite3.Connection(line 21). Change the return type tosqlite3.Connectionto match the docstring and comply with the project's type annotation requirements. Since the project requires Python >=3.12,connection.autocommit(line 33) is fully supported and the docstring claim is accurate for the target environment.

Docstring format doesn’t match Google style (“Parameters” vs “Args”).
Coding guidelines call for Google docstrings; consider switching Parameters: → Args: (and keep indentation consistent).
🤖 Prompt for AI Agents
In src/quota/cluster_quota_limiter.py around lines 19 to 29, the function/class
docstring uses "Parameters:" and does not follow the Google style; change
"Parameters:" to "Args:" and ensure each argument block uses Google-style
indentation (arg_name (type): description) aligned under Args: and any
multi-line descriptions are indented consistently by four spaces to match the
project's Google docstring conventions.

Fix Black formatting: remove trailing whitespace from docstring blank lines.
Lines 15, 20, and 23 contain trailing spaces on blank lines within the docstring. Run black src/quota/connect_pg.py to fix automatically.
Additionally, consider narrowing the return type from Any to a more specific psycopg2 connection type to align with the coding guideline requirement for complete type annotations.
🤖 Prompt for AI Agents
In src/quota/connect_pg.py around lines 13 to 26, the docstring contains
trailing whitespace on blank lines (lines 15, 20, 23) causing Black failures and
the function return type is overly broad (Any); remove the trailing spaces from
those blank lines (or run `black src/quota/connect_pg.py` to auto-fix) and
tighten the return annotation to the psycopg2 connection type (e.g.,
psycopg2.extensions.connection) by importing that type and updating the function
signature accordingly so the file passes formatting and uses a concrete
connection type.

40-47:__str__docstring is clear and accurate.
No issues.
35-37: The eager initialization pattern withself.connect()in__init__is appropriate for this local SQLite implementation. The concerns about blocking I/O do not apply to local database connections, and the code already ensures idempotency throughCREATE TABLE IF NOT EXISTS. The test suite verifies this pattern works safely with in-memory SQLite databases without issues. No changes are required.
