Add AWS S3 #224
Add AWS S3 #224
Conversation
This commit implements a new S3Store that uses AWS S3 as a distributed
key-value storage backend. The implementation follows the established
pattern from other distributed stores (DynamoDB, MongoDB) and provides:
- S3Store class for async operations using aioboto3
- Client-side TTL expiration checking (S3 lifecycle policies don't
support atomic TTL+retrieval)
- Comprehensive test suite with LocalStack integration
- Auto-generated sync library support
- Documentation updates in README
The store uses S3 objects with path format {collection}/{key} and
serializes ManagedEntry objects to JSON. TTL metadata is stored in
S3 object metadata and checked during retrieval operations.
Resolves #161

- Add S105 and S106 to ignored linting rules for test files (hardcoded test credentials) - Exclude S3Store from sync library generation (uses aioboto3 which is async-only) - Fix contextlib.suppress usage in S3 test file for proper async context handling - Remove generated sync S3 files S3Store follows the same pattern as DynamoDBStore - it's async-only because aioboto3 doesn't have a direct sync equivalent. The README correctly indicates S3 as async-only. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: William Easton <[email protected]>
- Remove unused _session instance variable - Improve exception handling to use ClientError and check error codes - Use ManagedEntry.is_expired property for consistency - Remove redundant s3_store fixture - Add HTTP_NOT_FOUND constant to avoid magic numbers - Add type ignores for boto response types Co-authored-by: William Easton <[email protected]>
S3 has a maximum key length of 1024 bytes. This fix ensures that long collection or key names are automatically hashed when they exceed safe limits (500 bytes each), keeping the total S3 key under 1024 bytes while maintaining uniqueness through hash suffixes. - Import hash_excess_length utility from key_value.shared.utils.sanitize - Add MAX_COLLECTION_LENGTH and MAX_KEY_LENGTH constants (500 bytes each) - Update _get_s3_key() to hash collection and key names if they exceed limits - Follows the same pattern used by MongoDB store for handling long names Fixes test_long_collection_name test which was failing with KeyTooLongError.

Adapt S3Store to match the serialization refactoring from PR #184: - Replace ManagedEntry.from_json() with self._serialization_adapter.load_json() - Replace managed_entry.to_json() with self._serialization_adapter.dump_json() - Leverage BasicSerializationAdapter automatically initialized by BaseStore Co-authored-by: William Easton <[email protected]>
…s_length - Add _truncate_to_bytes() helper that uses binary search to safely truncate strings at byte boundaries without splitting multi-byte UTF-8 characters - Add length_is_bytes parameter to sanitize_string() and hash_excess_length() to support byte-based length limits - Update S3Store to use length_is_bytes=True for proper S3 key length handling - Fixes KeyTooLongError when using multi-byte characters (emoji, CJK, etc.) This ensures S3 keys stay within the 1024-byte limit even with multi-byte UTF-8 characters.

- Add explicit client cleanup (set _client = None after __aexit__) - Remove deletion of expired objects during retrieval - Update both __aexit__ and _close for consistency Co-authored-by: William Easton <[email protected]>
- Close streaming body properly to prevent connection leaks - Add regional bucket creation support for non-us-east-1 regions Co-authored-by: William Easton <[email protected]>
- Add S3KeySanitizationStrategy and S3CollectionSanitizationStrategy classes - Remove automatic sanitization from _get_s3_key() - Add collection_sanitization_strategy and key_sanitization_strategy parameters to S3Store - Update S3Store to use BaseStore's _sanitize_collection_and_key() method - By default, collections/keys are not sanitized (matches new main pattern) - Update tests to use sanitization strategies - Update documentation to explain when/why to use strategies This aligns with the main branch refactor where stores no longer sanitize collections and keys by default, making sanitization opt-in via strategy parameters.

These fixtures use Docker containers with explicit 30-second ping timeouts, plus overhead for image pulling, container startup, and AWS SDK initialization. While memory stores have minimal setup overhead, the parameterized test suite accommodates distributed stores with legitimate infrastructure startup costs. The timeout is not masking issues but rather accommodating real integration test requirements typical for cloud service mocking.README.md (1)

48-53: Verify exception handling strategy — cluster.health() timeouts will not retry.The async source file was correctly modified with matching changes. However, exceptions from

Don't tear down caller-managed S3 clients
When the caller injects an already-entered S3 client (first overload), this block still invokes __aexit__ on it. That double-closes the caller’s context manager and can raise RuntimeError: __aexit__ already awaited or silently invalidate the client they still own. Track ownership (e.g., via the existing _raw_client reference) and only call __aexit__ on clients the store created itself, leaving externally supplied clients untouched.

56-65: API documentation addition follows established patterns.The S3Store section is properly positioned between DynamoDB and Elasticsearch, with consistent formatting and reference structure matching other store entries. No concerns here.
docs/stores.md (2)
400-400: Distributed stores table entry is well-formatted.The S3 entry correctly indicates Unstable status, async-only support, and aligns with the comprehensive documentation block that follows.
507-541: S3Store documentation is comprehensive and well-structured.The new section follows the established documentation pattern with clear usage examples, proper installation instructions, relevant use cases, and accurate S3 characteristics. However, I notice the AI summary mentions "duplicate S3Store documentation block...under Redis/Valkey sections," which is not visible in the provided code excerpt.
Please verify:
- Whether the S3Store documentation block appears twice in the full file (as indicated by the AI summary)
- If duplication exists, remove the duplicate to maintain documentation consistency

1-3: Now let me check the .gitignore and examine build_sync_library.py more closely:Based on all the evidence gathered, I can now provide the rewritten review comment. The key findings are:
- Systematic pattern: 100+ auto-generated files with the same header are committed across multiple stores, wrappers, adapters, and protocol subdirectories in production code
- Intentional architecture: This is not an isolated anomaly but a widespread, consistent pattern
- Best practice context: While standard practice suggests excluding auto-generated files from version control, there are valid exceptions when projects distribute generated code or avoid runtime build dependencies
The original review comment's concern appears to be based on general best practices, but the codebase evidence shows this is an intentional architectural choice consistent across all similar modules.
No changes required — auto-generated files are intentionally committed as part of the project's architecture.
The file follows the established pattern across the codebase. Over 100 auto-generated files from
build_sync_library.pyare systematically committed insrc/key_value/sync/stores/,src/key_value/sync/wrappers/,src/key_value/sync/adapters/, andsrc/key_value/sync/protocols/directories. This consistent approach indicates the project intentionally includes generated code in version control, likely to support distribution without requiring build-time dependencies. The filetree__init__.pyfile aligns with this established pattern.key-value/key-value-sync/src/key_value/sync/code_gen/stores/filetree/__init__.py (1)
1-12: LGTM - Clean package initializer.The package initializer correctly re-exports the three main public entities from the store module, with proper
__all__definition. The structure aligns with test imports and follows standard Python packaging patterns.key-value/key-value-sync/tests/code_gen/stores/filetree/test_filetree.py (2)
25-38: LGTM - Well-documented test fixture.The fixture properly creates a FileTreeStore with V1 sanitization strategies and a temporary directory. The documentation clearly explains the rationale for using these strategies.
40-43: LGTM - Appropriate test skip.The skip is correct for an unbounded store that doesn't evict entries. The reasoning is clearly documented.
key-value/key-value-sync/src/key_value/sync/code_gen/stores/filetree/store.py (4)
66-110: LGTM - Sanitization strategies correctly handle filesystem limits.The V1 sanitization strategies properly account for:
- Platform-specific path and filename length limits
- Reserved space for suffixes (
-info.jsonfor collections,.jsonfor keys)- Both path length and filename length constraints for keys
The logic is sound and aligns with the HybridSanitizationStrategy base class.
112-227: Implementation logic is sound, but AsyncPath must be replaced.The
DiskCollectionInfoclass correctly:
- Manages collection metadata and persistence
- Handles entry CRUD operations with proper sanitization
- Provides serialization to/from JSON
- Includes factory methods for loading from disk
However, all
AsyncPathtype annotations and usages must be replaced with standardPathto work in synchronous code.This depends on fixing the async/sync mismatch flagged in the imports.
240-320: FileTreeStore initialization logic is correct.The store properly:
- Creates and resolves data/metadata directories
- Initializes collection info tracking
- Delegates to the base class with appropriate adapters
The warning documentation correctly notes this is for development/testing only.
Note: AsyncPath usage must be converted to Path as part of the overall async/sync fix.
322-405: Store operations correctly implement BaseStore interface.The override methods properly:
- Set up collections with sanitization
- Delegate entry operations to DiskCollectionInfo
- Return appropriate types and values
Note: Depends on fixing AsyncPath → Path throughout.

Critical: Incomplete code generation from async to sync.
This file claims to be auto-generated by build_sync_library.py from an async original, but the conversion is incomplete. The sync version still contains:
- Async library imports (
aiofile,anyio) - Async patterns used synchronously
- Missing dependencies causing import failures
This prevents the code from running and is blocking the PR.
Would you like me to:
- Generate a script to verify the async→sync conversion requirements?
- Help investigate why the code generation failed?
- Provide a complete manual conversion of the async patterns to sync equivalents?
The core logic appears sound—this is purely a code generation/conversion issue.

Apply this diff to fix the imports:

Critical: Async file operations in synchronous functions.
The read_file and write_file functions use aopen (async file operations) with synchronous context managers (with instead of async with) and without await keywords. This will fail at runtime.
For sync code, these should use standard open():

243-243: LGTM: More resilient exception matching.The change from matching a specific exception string to the broader substring "already_exists_exception" makes the code more resilient to variations in Elasticsearch error messages across different versions and deployment modes (e.g., serverless). Since the exception is already scoped to
BadRequestError, this won't catch unrelated errors.key-value/key-value-sync/tests/code_gen/stores/elasticsearch/test_elasticsearch.py (1)
4-4: LGTM: Standard logging setup.The logging import and module-level logger are correctly configured and used appropriately in the enhanced
ping_elasticsearchfunction.Also applies to: 37-37
key-value/key-value-aio/tests/stores/elasticsearch/test_elasticsearch.py (2)
1-1: LGTM!Good addition of logging infrastructure to support the enhanced diagnostics in
ping_elasticsearch().Also applies to: 36-37
47-57: Exception handling and timeout extension implemented correctly.The implementation now matches the established pattern from
ping_mongodb()and correctly handles transient failures by returningFalsefor retries. The timeout extension from 10s to 15s addresses the PR feedback.One minor consideration: catching
Exceptionis quite broad. If you want to be more specific, consider catching only the expected Elasticsearch exceptions (e.g.,ConnectionError,TransportError,ApiError). However, the current approach is acceptable given that any failure during health check should trigger a retry.key-value/key-value-aio/src/key_value/aio/stores/elasticsearch/store.py (1)
271-271: No issues found—this is a backwards-compatible version fix.The broadened substring match from
"index_already_exists_exception"to"already_exists_exception"is intentional and safe. Elasticsearch changed exception naming between versions: older clients returnindex_already_exists_exceptionwhile newer ones returnresource_already_exists_exception. Both variants contain the substringalready_exists_exception, so the current check handles both old and new versions. The context (insideindices.create()error handling) is narrow enough that no false positives from unrelated exceptions are possible.

🧹 Nitpick | 🔵 Trivial
Good addition: Health check ensures cluster readiness.
The enhanced ping_elasticsearch function now properly waits for the cluster to reach yellow status before proceeding, which prevents test failures due to the cluster not being fully ready. The 15-second timeout aligns with the user's request in the PR comments.
Consider simplifying the control flow by removing the else clause:
if es_client.ping():
logger.info("Elasticsearch pinged, wait for yellow status")
try:
es_client.cluster.health(wait_for_status="yellow", timeout="15s")
logger.info("Elasticsearch is ready")
+ return True
except Exception as e:
logger.warning(f"Cluster health check failed: {e}")
return False
- else:
- return True
return FalseThis removes the try-except-else pattern in favor of a simpler early return, making the logic slightly easier to follow.

around lines 48 to 58, the try-except-else control flow is more complex than
needed; simplify by removing the else clause and return True immediately after a
successful cluster.health() call inside the try block, while keeping the except
to log the warning and return False; retain the final return False for the
ping==False path.

Test Failure AnalysisSummary: Elasticsearch tests are timing out when run with oldest dependencies. The tests exceed the 10-second pytest timeout during Elasticsearch index operations. Root Cause: The Elasticsearch tests (specifically for version 9.2.0) are timing out during test execution with the oldest supported dependencies. The failures occur in:
The logs show Elasticsearch is returning HTTP 503 (Service Unavailable) errors when trying to access the newly created index, suggesting the index isn't ready for operations immediately after creation. The tests hit the 10-second timeout while waiting for retries. Suggested Solution: This is a test infrastructure timing issue, not related to the S3 changes in this PR. To fix:
The issue appears specifically when using oldest dependencies, suggesting it may be related to compatibility between:
Detailed AnalysisError DetailsThe test fails with: Log EvidenceThe index was created successfully (status 400 suggests it already exists from cleanup), but when trying to read from it, Elasticsearch returns 503 repeatedly, causing retries and eventual timeout. Failed Job
Test Matrix Results
This suggests the issue is specific to the combination of oldest supported dependency versions. Related FilesFiles relevant to this failure:
Note: This issue is unrelated to the S3 implementation added in this PR. All other tests (including S3) are passing. The Elasticsearch timeout issue exists only when running with oldest dependencies and appears to be a pre-existing test infrastructure issue. |
Test Failure AnalysisSummary: Elasticsearch 9.2.0 tests are timing out (>10s) during test execution, causing 5 test failures. Root Cause: The Elasticsearch tests for version 9.2.0 are hitting the 10-second pytest timeout. The tests are:
Looking at the logs, these same tests passed successfully earlier in the test run (around 15:16:47-15:16:50 UTC), but then failed with timeouts when run again later (around 15:19:40+ UTC). This pattern suggests a race condition or resource contention issue when tests are run in parallel by pytest-xdist. The recent commit Suggested Solution: Option 1: Increase test timeout for Elasticsearch (Quick fix) In import pytest
pytestmark = [
pytest.mark.timeout(20), # Elasticsearch needs more time for cluster operations
]Option 2: Disable parallel execution for Elasticsearch (More reliable) pytestmark = [
pytest.mark.timeout(20),
pytest.mark.xdist_group(name="elasticsearch"), # Run all ES tests serially
]Option 3: Investigate and fix the root cause (Best long-term)
Would recommend investigating the Detailed AnalysisTest Results
Timeline EvidenceFirst run (PASSED): Second run (FAILED): This shows that the same tests run twice (likely due to pytest parametrization or test collection), passing the first time but timing out the second time. Recent ChangesCommit Why This Is Unrelated to S3 PRAll S3 tests (132 tests) passed successfully. The Elasticsearch timeout issue is a pre-existing flaky test problem that has been reported in previous issues (#218, #201) and previous comments on this PR. Related FilesFiles to modify:

Note: This is a flaky test infrastructure issue specific to Elasticsearch 9.2.0, not related to the S3 implementation added in this PR. Consider either:

@claude i think we decided elsewhere that if the user provides us a client that we own that client? does that seem right or wrong? Also can you remove some of the excessive code comments that have been put in place? we dont need comments for obvious stuff |

Claude finished @strawgate's task —— View job Review Complete ✅Tasks
Client Ownership DecisionAnswer: YES, we own the client lifecycle even when the user provides it. After reviewing both S3Store and DynamoDBStore, this is the established pattern in the codebase:
The pattern works because:
This means we take ownership of any client passed to us. Both DynamoDB and S3 follow this pattern consistently. Code Cleanup SummaryRemoved excessive/obvious inline comments from the S3 store implementation: Removed:
Kept:
The code is now cleaner and more maintainable, with only meaningful comments that explain non-obvious behavior. Branch: claude/issue-161-20251029-0140 | Commit: f14500a | View job |
- Remove obvious comments that state what the code already shows - Keep only non-obvious comments (e.g., region-specific AWS logic) - Simplify constant comments to be more concise - Remove type-hinting comments where type is already declared Co-authored-by: William Easton <[email protected]>
