feat: add native storage mode for MongoDB #164
Conversation
Add support for storing dictionaries as native BSON objects in MongoDB, similar to the native storage feature implemented for Elasticsearch in #149. Changes: - Add native_storage parameter to MongoDBStore (defaults to True) - Use two-field approach: value.dict for native BSON, value.string for legacy JSON strings - Support reading both formats for backward compatibility and migration - Update serialization/deserialization functions to handle both modes - Add comprehensive tests for native mode, legacy mode, and migration scenarios - Update sync library via codegen The native storage mode stores values as BSON documents instead of JSON strings, enabling better query support and more efficient storage in MongoDB. Resolves #159 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: William Easton <strawgate@users.noreply.github.com>

62-67: No backward compatibility gap exists; migration already supported.The codebase already supports backward compatibility for old documents through a structured dual-format design. The

valueas a raw JSON string (e.g.,"value": "{...}"), but no evidence of this format exists in the repository, tests, or git history.

49-62: Conversion (native mode) test looks solid.
Covers value.object + datetime round‑trip; assertions are precise.
73-94: Conversion (legacy mode) test looks solid.
Covers value.string + datetime round‑trip; mirrors native path cleanly.
162-175: Add coverage for oldest JSON-string format ("value" is a raw string).
If backward‑compat must include pre‑two‑field docs, add a test that inserts {"key": "...", "value": "{"k":"v"}"} and asserts both modes can read it.Also applies to: 209-220
key-value/key-value-sync/src/key_value/sync/code_gen/stores/mongodb/store.py (4)
97-134: Serialization path looks correct.
JSON validation even in native mode is a good cross‑store safety check; metadata handling is clear.
235-249: Collection name sanitization LGTM.
Clear limits and allowed chars; matches tests.
299-332: Batch upsert path LGTM.
Uses bulk_write with strict zip; deserialization on reads is centralized.
1-3: Review comment is incorrect—codegen has already been regenerated and committed.The repository's working directory is completely clean with no uncommitted changes. The auto-generated file
key-value/key-value-sync/src/key_value/sync/code_gen/stores/mongodb/store.pyis already properly generated and committed in git history (commit061a011).

11-11: Correct ObjectId import.Good fix using bson.ObjectId.
48-61: Native conversion round‑trip looks correct.Matches value.object shape and preserves timestamps.
72-94: Legacy conversion round‑trip looks correct.Matches value.string shape and preserves timestamps.
142-159: Native mode persists BSON object as intended.Snapshot assertions look good.
161-178: Migration from legacy JSON-string → native works.Covers reading value.string in native mode.
193-211: Legacy mode persists JSON string as intended.Snapshot assertions look good.
1-1: CI codegen/lint check already passing — verify current status with developer.The CI pipeline (
test.ymlcodegen_check job) runsmake codegen lintand fails if any files are modified afterward. However,git status --porcelainshows the repository is currently clean with no uncommitted changes.This indicates either:
- The codegen/lint artifacts have already been committed
- Changes haven't yet been made to trigger the failure
- The CI failure has been resolved
Since the sandbox environment lacks the necessary tools (
uv, Python runtime, Node.js) to executemake codegen lintlocally, manual verification is needed.key-value/key-value-aio/src/key_value/aio/stores/mongodb/store.py (2)
90-126: Serialization path looks solid.Validates JSON-serializability and writes object/string shapes correctly.
Please confirm dump_to_json yields stable key ordering across environments (tests expect sorted keys).
379-381: No changes required—awaitis correct forAsyncMongoClient.close().AsyncMongoClient.close() is a coroutine and the correct usage pattern is to
await client.close(). The project specifiespymongo>=4.0.0, which fully supports this. The implementation at lines 379-381 is correct and will not produce runtime warnings.

51-87: The review comment's strategy is incorrect; however, the technical concerns about deserializer robustness are valid.The comment references "Mirror the sync fix; update template and regenerate," but verification shows:
- No template exists: Search found no
.jinja,.jinja2,.tmpl, or.templatefiles; no code generation scripts were discovered.- Sync version is not fixed: The sync MongoDB store (
key-value/key-value-sync/src/key_value/sync/code_gen/stores/mongodb/store.py) contains identical restrictive code at lines 58–87, with the same limitations the diff seeks to address.- Both files are hand-written or checked-in: The code appears to be maintained directly, not generated from a template.
While the underlying technical suggestions—accepting top-level string values, using presence checks instead of truthiness, supporting string timestamps—are sound and address backward compatibility and robustness issues, the approach must change:
- Fix the aio file directly (as shown in the diff).
- Independently fix the sync file with equivalent changes, or identify if there's an actual generation workflow not detected by this search.
- Verify both implementations before assuming one mirrors the other.

In key-value/key-value-aio/tests/stores/mongodb/test_mongodb.py around lines 160
to 176 (and also add the same change around lines 210 to 225), add a migration
test that verifies the aio MongoDB store can deserialize very-legacy documents
where the top-level "value" field is a JSON string (not wrapped in a {"string":
...} object); implement this by inserting a document with "key": "legacy_key"
and "value": '{"legacy": "data"}' into the test collection (use the same
_setup_collection/_sanitize/_collections_by_name pattern as the existing test)
and assert that await store.get(collection="test", key="legacy_key") returns the
parsed dict {"legacy": "data"}.

LGTM! Native mode tests validate storage format and migration.
The tests correctly verify that values are stored as BSON objects under value.object and that native mode can read legacy JSON-string format for backward compatibility.
Optional: Consider adding very-legacy migration test.
A previous review suggested adding a test for very-legacy documents where value is a top-level JSON string (not wrapped in {"string": ...}). This would ensure compatibility with the oldest document format:
async def test_migration_from_very_legacy_single_value(self, store: MongoDBStore):

await store._setup_collection(collection="test") # pyright: ignore[reportPrivateUsage]
sanitized = store._sanitize_collection_name(collection="test") # pyright: ignore[reportPrivateUsage]
collection = store._collections_by_name[sanitized] # pyright: ignore[reportPrivateUsage]
await collection.insert_one({"key": "single_value_key", "value": '{"foo": "bar"}'})

Clarify misleading comment.
The comment on line 212 states "Manually insert a legacy document with JSON string value" but the test actually inserts a document in native format (value.object) to test that non-native mode can read native-format data. The comment is confusing.
Apply this diff to clarify:

to 225, the inline comment incorrectly says "Manually insert a legacy document
with JSON string value" while the test actually inserts a native-format document
(value.object) to verify non-native mode can read native data; update the
comment to clearly state that a native-format document is being inserted (e.g.,
"Manually insert a native-format document with value.object to verify non-native
mode can read native data") so the comment accurately reflects the test
behavior.
