Ai Milvus Store Laravel Package
symfony/ai-milvus-store
Milvus Store adds Milvus vector database support to Symfony AI Store. Connect to a Milvus instance, create collections, insert vectors, run similarity searches, and apply boolean filter expressions using Milvus REST APIs.
Milvus Store integrates Milvus as a vector database backend for Symfony AI Store, enabling fast similarity search and metadata filtering for your embeddings. Use it to create collections, insert vectors, and run searches through Milvus’ REST API while staying aligned with Symfony’s store abstractions.
- Milvus vector store implementation for Symfony AI
- Create and manage collections for embeddings
- Insert entities/vectors with associated metadata
- Perform similarity search with optional boolean filters
- Built on Milvus REST v2.5 endpoints and docs
Frequently asked questions about Ai Milvus Store
- How do I install Symfony AI Milvus Store in a Laravel project?
- Use Composer to install the package with `composer require symfony/ai-milvus-store`. Since it’s part of Symfony AI, ensure you also have `symfony/ai` installed. Laravel projects can integrate it via Symfony’s bridge packages like `symfony/ux-live-component` or by manually configuring the AI client to use the Milvus store.
- Which Laravel versions support Symfony AI Milvus Store?
- The package is built for Symfony AI, which targets PHP 8.1+. Laravel 10+ is recommended due to its compatibility with Symfony components. For Laravel 9, check Symfony AI’s version constraints, as some newer features may require updates.
- Can I use Milvus Store with existing Laravel database migrations?
- No, Milvus Store manages collections via Milvus’ REST API, not Laravel migrations. Collections must be created programmatically or via Milvus CLI/tools. Use the store’s `createCollection()` method in a service or command during deployment.
- How do I perform a hybrid search (vector + metadata filtering) in Laravel?
- Use the `search()` method on the Milvus store instance, passing a `BooleanExpression` for metadata filters. Example: `$results = $milvusStore->search($vector, 10, new BooleanExpression('user_id == 42 && is_active == true'))`. The package abstracts Milvus’ filter syntax into Symfony’s AI store interface.
- What happens if Milvus is down during a Laravel request?
- The package throws exceptions on Milvus failures. Implement retry logic (e.g., Symfony’s `RetryStrategy`) or a fallback (e.g., local cache or a secondary store like `symfony/ai-postgresql-store`). For critical apps, consider circuit breakers like `symfony/http-client`'s `CircuitBreakerMiddleware`.
- Is Milvus Store suitable for large-scale Laravel applications with high QPS?
- Milvus handles high throughput, but network latency may impact Laravel. Optimize by batching inserts/searches, using Milvus’ async APIs, or caching frequent queries in Redis. Monitor Milvus metrics (e.g., QPS, latency) via Prometheus or custom logging.
- How do I handle schema changes in Milvus collections for Laravel models?
- Milvus collections require upfront schema definitions. For Laravel, define schemas in a config file or service. To modify schemas (e.g., adding fields), use Milvus’ `AlterCollection` API, but note this may require downtime or data migration. Avoid dynamic schema changes in production.
- What are the alternatives to Milvus Store for Laravel vector search?
- Consider `symfony/ai-postgresql-store` (pgvector), `meilisearch/meilisearch-php`, or `qdrant/qdrant-client`. For Laravel-native options, explore `spatie/laravel-ai` or `typefit/laravel-embeddings`. Milvus excels in scalability but requires self-hosting or cloud setup.
- Can I use Milvus Store with Laravel’s queue system for async operations?
- The package is synchronous, but you can wrap Milvus operations in Laravel queues. For example, dispatch a job to insert vectors into Milvus using `dispatch(new InsertVectorsJob($vectors))`. Use Symfony Messenger for async workflows if integrating deeper with Symfony AI.
- How do I test Milvus Store in a Laravel CI pipeline?
- Mock the Milvus client using Symfony’s `HttpClientMock` or a test double. For integration tests, spin up a local Milvus instance (e.g., Docker) or use a staging Milvus endpoint. Test edge cases like connection drops, invalid filters, and large payloads. Avoid hitting production Milvus in tests.
