IVectorStore
Description
Defines the contract for interacting with a specific vector database or storage backend. Implementations will wrap specific clients (e.g., Pinecone client, Weaviate client, in-memory store logic).
Methods
checkHealth()
checkHealth():
Promise<{details?:any;isHealthy:boolean; }>
Defined in: packages/agentos/src/rag/IVectorStore.ts:357
Checks the operational health of the vector store provider. This might involve pinging the service, checking connection status, or verifying authentication.
Returns
Promise<{ details?: any; isHealthy: boolean; }>
A promise that resolves with the health status.
details can include specific error messages or status information.
Async
collectionExists()?
optionalcollectionExists(collectionName):Promise<boolean>
Defined in: packages/agentos/src/rag/IVectorStore.ts:347
Checks if a collection with the given name exists in the vector store.
Parameters
collectionName
string
The name of the collection to check.
Returns
Promise<boolean>
A promise that resolves with true if the collection exists, false otherwise.
Async
Throws
If the check fails for reasons other than existence (e.g., connection issue).
createCollection()?
optionalcreateCollection(collectionName,dimension,options?):Promise<void>
Defined in: packages/agentos/src/rag/IVectorStore.ts:323
Creates a new collection (or index, class, etc.) in the vector store. This is often necessary before documents can be upserted into it, depending on the provider.
Parameters
collectionName
string
The name of the collection to create.
dimension
number
The dimensionality of the vector embeddings that will be stored in this collection.
options?
Optional parameters for collection creation, such as similarity metric or provider-specific settings.
Returns
Promise<void>
A promise that resolves when the collection is successfully created.
Async
Throws
If collection creation fails (e.g., name conflict and not overwriting, invalid parameters).
delete()
delete(
collectionName,ids?,options?):Promise<DeleteResult>
Defined in: packages/agentos/src/rag/IVectorStore.ts:306
Deletes documents from a specified collection by their IDs or by a metadata filter.
Parameters
collectionName
string
The name of the collection to delete documents from.
ids?
string[]
An array of document IDs to delete.
options?
Optional parameters, including metadata filters or a deleteAll flag.
If ids are provided, options.filter might be ignored or combined,
depending on store behavior. Use with caution.
Returns
Promise<DeleteResult>
A promise that resolves with the result of the delete operation.
Async
Throws
If the delete operation fails.
deleteCollection()?
optionaldeleteCollection(collectionName):Promise<void>
Defined in: packages/agentos/src/rag/IVectorStore.ts:337
Deletes an entire collection from the vector store. This is a destructive operation.
Parameters
collectionName
string
The name of the collection to delete.
Returns
Promise<void>
A promise that resolves when the collection is successfully deleted.
Async
Throws
If collection deletion fails.
getStats()?
optionalgetStats(collectionName?):Promise<Record<string,any>>
Defined in: packages/agentos/src/rag/IVectorStore.ts:378
Optional: Retrieves statistics about a specific collection or the store itself. The structure of the returned statistics is provider-dependent.
Parameters
collectionName?
string
Optional: The name of the collection to get stats for. If omitted, may return store-wide stats if supported.
Returns
Promise<Record<string, any>>
A promise that resolves with a statistics object.
Async
Throws
If fetching statistics fails.
initialize()
initialize(
config):Promise<void>
Defined in: packages/agentos/src/rag/IVectorStore.ts:259
Initializes the vector store provider with its specific configuration. This method must be called before any other operations can be performed. It sets up connections, authenticates, and prepares the store for use.
Parameters
config
The configuration object specific to this vector store provider.
This is typically a more specific type that extends VectorStoreProviderConfig.
Returns
Promise<void>
A promise that resolves when initialization is complete.
Async
Throws
If initialization fails (e.g., invalid configuration, connection error, authentication failure).
query()
query(
collectionName,queryEmbedding,options?):Promise<QueryResult>
Defined in: packages/agentos/src/rag/IVectorStore.ts:288
Queries a specified collection for documents similar to the provided query embedding.
Parameters
collectionName
string
The name of the collection to query.
queryEmbedding
number[]
The query vector embedding.
options?
Optional parameters for the query operation, including filters and topK.
Returns
Promise<QueryResult>
A promise that resolves with the query results.
Async
Throws
If the query operation fails.
shutdown()
shutdown():
Promise<void>
Defined in: packages/agentos/src/rag/IVectorStore.ts:366
Gracefully shuts down the vector store provider, releasing any resources such as database connections or client instances.
Returns
Promise<void>
A promise that resolves when shutdown is complete.
Async
upsert()
upsert(
collectionName,documents,options?):Promise<UpsertResult>
Defined in: packages/agentos/src/rag/IVectorStore.ts:272
Upserts (inserts or updates) a batch of documents into a specified collection. If a document with the same ID already exists, it is typically updated; otherwise, it's inserted.
Parameters
collectionName
string
The name of the collection (or index, class, etc.) to upsert documents into.
documents
An array of documents to upsert.
options?
Optional parameters for the upsert operation.
Returns
Promise<UpsertResult>
A promise that resolves with the result of the upsert operation.
Async
Throws
If the upsert operation fails critically.
