Safety notes	— missing	✓Chroma can make retrieval easier, but vector, hybrid, full-text, and regex search results still require evaluation for relevance, freshness, permission fit, and hallucination risk. Retrieved documents, metadata, and embeddings can influence agent actions; review chunking, filters, collection boundaries, and prompt assembly before using results in automated workflows. Duplicate IDs, mismatched embedding dimensions, stale records, partial updates, and deleted-source drift can produce confusing or incorrect retrieval behavior if ingestion is not controlled. Metadata filters are useful access boundaries only when the application enforces them consistently; do not rely on model instructions alone to prevent cross-tenant or cross-project retrieval. Local and self-hosted deployments still need normal database operations including authentication, network exposure review, backups, resource limits, monitoring, and recovery tests. Chroma Cloud, embedding providers, and connected AI applications may add account, billing, availability, and organization-policy dependencies beyond the open-source database package.	✓LanceDB can support RAG, multimodal search, recommendation systems, and AI/ML data workflows, but retrieved records still need relevance checks, freshness checks, permission filtering, and evaluation. Vector search, full-text search, SQL filters, hybrid retrieval, and reranking can return plausible but incomplete context when chunking, filters, indexes, or embedding models are poorly matched to the task. Local embedded databases reduce server overhead, but they still need controlled file permissions, backup practices, storage monitoring, version cleanup, and safe handling in shared development environments. Cloud, REST, and remote deployments add network exposure, account, billing, latency, availability, and access-control decisions beyond the open-source local package. Index choices, GPU-assisted index building, automatic versioning, and zero-copy workflows can improve performance, but operators should benchmark recall, latency, storage size, and update behavior before production use. Agent outputs, generated summaries, and automated decisions that depend on LanceDB results should remain attributable to source records and reviewable by the owning team.	✓Milvus can power RAG, agent memory, recommendation systems, image search, and multimodal retrieval, but retrieved context still needs relevance checks, freshness checks, permission filtering, and human-reviewable evaluation. ANN index choices, quantization, memory mapping, GPU indexing, sparse retrieval, hybrid search, and reranking trade off latency, recall, cost, and operational complexity. Embedding drift, schema changes, stale partitions, deleted-source drift, duplicate IDs, and mismatched vector dimensions can produce confusing retrieval results if ingestion is not controlled. Multi-tenancy, access controls, TLS, replicas, and Kubernetes-native deployment features are production building blocks, not substitutes for application-level permission checks. Local, standalone, cluster, and managed deployments need explicit network exposure, storage durability, backup, monitoring, compaction, upgrade, and resource-limit decisions. Agent actions, chatbot answers, generated summaries, and recommender outputs that use Milvus results should remain attributable to source records and reviewable before affecting users or production workflows.
Privacy notes	— missing	✓Chroma collections may store source documents, document chunks, metadata, IDs, embeddings, multimodal references, query text, and retrieval results that can reveal sensitive project context. Embeddings can leak information about the original data and should be governed with the same retention, deletion, access-control, and backup policies as the documents they represent. Embedding providers, Chroma Cloud, hosted model routes, or application telemetry may receive document or query content depending on how ingestion and search are configured. Metadata can include user identifiers, source names, document provenance, internal labels, and permission fields; define redaction and minimization rules before ingestion. Retrieval logs, failed queries, evaluation traces, and agent transcripts can re-expose stored data outside Chroma, so downstream systems need their own retention and access policies.	✓LanceDB tables may store vectors, source records, metadata, text, images, video, point clouds, generated context, search results, query records, and table versions that can expose sensitive project or user data. Embeddings and multimodal features can encode information from source content and should follow the same retention, deletion, backup, tenant-isolation, and access policies as the original records. Embedding providers, rerankers, LanceDB Cloud, REST services, observability systems, and downstream agent applications may process prompts, queries, files, metadata, or retrieved context depending on configuration. Versioned data and local database files can retain older records after application-level changes unless teams explicitly define compaction, deletion, and cleanup behavior. Teams should define who can inspect retrieval traces, failed-query artifacts, local database directories, table versions, logs, backups, and generated answers before exposing LanceDB-backed context to Claude-adjacent workflows.	✓Milvus collections may store vector embeddings, sparse vectors, scalar fields, metadata, document chunks, image or multimodal references, query records, and retrieval results that reveal sensitive project or user context. Embeddings can encode information about source records and should follow the same retention, deletion, backup, access-control, and tenant-isolation policies as the underlying data. Embedding providers, reranking services, generative models, Zilliz Cloud, observability systems, and downstream agent applications may process prompts, queries, source snippets, or retrieved context depending on configuration. Metadata fields used for filtering can expose user identity, source systems, document provenance, permission groups, customer labels, or business classifications if exported or logged carelessly. Teams should define who can view retrieval traces, query logs, failed-search artifacts, benchmark datasets, backups, and generated answers before exposing Milvus-backed context to Claude-adjacent workflows.
