The recently opened issues for the software project indicate a variety of concerns, ranging from feature requests to bug reports. A common theme among these issues is the need for improvements in the functionality and reliability of the software. Notably, issue #2929 requests a graceful shutdown feature for local setup, which could be significant for ensuring data integrity and system stability. Issue #2922 discusses problems with pagination methods and related sorting methods in vector and full-text search queries, which could potentially impact the usability and performance of the software. Issue #2913 requests a feature to check shard compatibility on recovery, which could help prevent data inconsistencies and errors. Issue #2893 reports a problem with restoring large collections in a distributed deployment, which could be a major concern for scalability and data recovery.
The older open issues present a range of concerns, including feature requests, bug reports, and discussions about potential enhancements. For example, issue #804 discusses the potential for improving the compression scheme for RocksDB, while issue #1132 requests the ability to add new vector fields after collection creation. Issue #1167 suggests the implementation of automatic benchmarking on all PRs to track performance and detect potential regressions. Recently closed issues include #2796, which tracked tasks for integrating the sparse vector index into the engine, and #2790, which tracked the development of a new type of search: discovery. A common theme among these issues is the continuous improvement and enhancement of the software's functionality, performance, and reliability.
There are 188 open pull requests. The most recent ones are actively being discussed and updated, indicating an active development environment. The pull requests cover a range of topics, including build cache optimization, response status code handling, shard transfer improvements, test enhancements, and custom TLS certificate support.
Build Optimization: PR #2935 aims to reduce build cache invalidation, which is causing expensive rebuilds. This PR is crucial for improving the build process efficiency.
Performance Improvement: PR #2931 proposes to increase the maximum visited-list pool size from 16 to 128 to address significant degradation in tail latencies observed during concurrent searches.
API Compatibility: PR #2928 replaces response status code enums with strings to address issues with the Python client generator.
Shard Transfer: PR #2926 and PR #2924 are working on improving the abort/cancellation support for shard transfer. This is a significant area of focus, as it impacts the reliability and robustness of the system.
Testing: PR #2925 and PR #2902 are adding extra tests for Sparse Vector Index and snapshot transfer during updates respectively. This indicates a strong focus on improving the test coverage and reliability of the software.
Custom TLS Certificate Support: PR #2895 adds custom TLS certificate support for remote snapshot downloads to snapshot recover APIs. This is a significant security enhancement for the project.
Complex Discussions: Some pull requests, such as PR #2918 and PR #2895, have complex discussions that could indicate potential challenges or disagreements in the implementation approach.
Backward Compatibility: PR #2909 mentions the need for a migration in the Python client due to changes in data structures, which could potentially impact existing users.
Shard Key Routing: PR #2909 is implementing custom shard routing in point-level APIs. The impact and effectiveness of this change will need to be evaluated.
Fuzz Testing: PR #2889 is introducing a simple fuzz test. The effectiveness and coverage of this fuzz test will need to be evaluated.
No worrying anomalies were identified in the recent open pull requests.
