Highlights in this release are the possibility to export/import the DB to/from object storage like S3, a way to run a negative query and either filter or subtract the results from the regular query results, and the license change from AGPL to MPL. But many other additions, improvements and important fixes made it into this release as well, all without breaking changes:

Added

• Added DB.ExportToWriter() to allow users to pass any io.Writer implementation for the DB export, not just a file. This allows for example to export the DB to AWS S3 or compatible services (like Ceph, MinIO etc.). (PR #71)
• Added DB.ImportFromReader() to allow users to pass any io.ReadSeeker implementation for the DB import, not just a file. This allows for example to import the DB from AWS S3 or compatible services (like Ceph, MinIO etc.). (PR #72)
• Added example code for S3 export/import with the ⬆️ new methods (PR #73)
• Added Azure OpenAI compatibility (PR #74 by @iwilltry42)
• Added lint job in GitHub Action (PR #82 by @erikdubbelboer)
• Added the feature to run a negative query and either filter or subtract them from the regular query results (PR #80 by @erikdubbelboer)
  • This PR also added the new DB.QueryWithOptions method and related options structs and constants for future extensibility without breaking the parameter list of the query method!
• Added option to only import/export selected collections to/from a DB (PR #88 by @iwilltry42)
• Added Google / GCP Vertex AI embedding function (PR #91 by @iwilltry42 and #93)
• Added new embedding model constants for Jina and Mixedbread (PR #94)
• Added Collection.GetByID() to get a document for a known ID (PR #97, for issue #95)

Improved

• Changed license from AGPL to MPL (PR #87)
• Updated golangci-lint in CI to its latest version (PR #99)
• Added Go 1.23 to the CI build matrix (PR #98)
• Improved Godoc (PR #100)

Fixed

• The Collection.QueryEmbedding() call assumed/expected the query embedding from the parameter to be normalized already, but it wasn't documented and it's also inconvenient for users who use an embedding model/API that doesn't return normalized embeddings. Now we check whether the embedding is normalized and if it's not then we normalize it. (PR #77)
  • (Currently chromem-go only does cosine similarity, and document embeddings are already being normalized, so the query embedding has to be normalized as well. In the future we might offer other distance functions or allow to inject your own and make the normalization optional)
• Fixed test panic on unexpected pass (PR #78)
• Fixed out of range panic on query (PR #79)
• Fixed all golangci-lint warnings (PR #82 by @erikdubbelboer)
• Fixed grammar and inconsistent receiver names (PR #85 by @codefromthecrypt)
• Fixed link in Godoc (PR #89)

New Contributors

• @codefromthecrypt made their first contribution in #83

Highlights in this release are an extended interface, experimental WebAssembly bindings, and the option to use a custom Ollama URL. But also the fact that three people contributed to this release! Thank you so much! 🙇‍♂️

Added

• Added Collection.Delete() to delete documents from a collection (PR #63 by @iwilltry42)
• Added an experimental WebAssembly binding (package wasm) and example (PR #69)

Improved

• Use prefixes for nomic-embed-text model in RAG-Wikipedia-Ollama example (PR #49, #65)
  • Thanks @rinor for pointing out the bug!
• Made Ollama URL configurable (PR #64 by @erikdubbelboer)
• Added building of code examples to CI (PR #66)
• Improved RAG template (PR #67)

Breaking changes

• NewEmbeddingFuncOllama now requires a second parameter for the base URL. But it can be empty to use the default which was also used in the past.

New Contributors

• @rinor made their first contribution by suggesting a fix in #49
• @iwilltry42 made their first contribution in #63
• @erikdubbelboer made their first contribution in #64

Highlights in this release are query performance improvements (5x faster, 98% fewer memory allocations), export/import of the entire DB to/from a single file with optional gzip-compression and AES-GCM encryption, optional gzip-compression for the regular persistence, a new code example for semantic search across 5,000 arXiv papers, and an embedding func for Cohere.

• Extended parameter validation (PR #50, #51)
• Simplified unit tests (PR #55)
• Improve NewPersistentDB() path handling (PR #56)
• Improve loading of persistent DB (PR #57)
• Increased unit test coverage in various of the other listed PRs

Fixed

• Fixed path joining (PR #44)

Breaking changes

• Due to vectors now being normalized at the time of adding the document to the collection instead of when querying, the persisted data from prior versions is incompatible with this version (PR #47)

v0.5.0 (2024-03-23)

Compare

Choose a tag to compare

Highlights in this release are optional persistence, an extended interface, support for creating embeddings with Ollama, the exporting of the Document struct, and more Go-idiomatic methods to add documents to collections.

Added

• Extended the interface:
  • DB.ListCollections() (PR #12)
  • DB.GetCollection() (PR #13 + #19)
  • DB.DeleteCollection() (PR #14)
  • DB.Reset() (PR #15)
  • DB.GetOrCreateCollection() (PR #22)
  • Collection.Count() (PR #27)
  • Document struct, NewDocument() function, Collection.AddDocument() and Collection.AddDocuments() methods (PR #34)
    • More Go-idiomatic alternatives to Collection.Add()
• Added various unit tests (PR #20, #39)
• Added optional persistence! Via multiple PRs:
  • Write in PR #23, #24, #31
  • Read in PR #25
  • Delete in PR #26
• Added support for creating embeddings with Ollama (PR #32)
• Added example documentation (PR #42)

Improved

• Improved example (PR #11, #28, #33)
• Stop exporting Collection.Metadata (PR #16)
  • Goal: Prevent direct modifications which could cause data races in case of the user doing a modification while chromem-go for example ranges over it during a Collection.Query() call.
• Copy metadata in constructors (PR #17)
  • Goal: Prevent direct modifications which could cause data races in case of the user doing a modification while chromem-go for example ranges over it.
• Improved CI (PR #18)
  • Add Go 1.22 to test matrix, update used GitHub Action from v4 to v5, use race detector during tests
• Reorganize code internally (PR #21)
• Switched to newer recommended check for file related ErrNotExist errors (PR #29)
• Added more validations in several existing methods (PR #30)
• Internal variable renamed (PR #37)
• Fail unit tests immediately (PR #40)

Fixed

• Fixed metadatas validation in Collection.AddConcurrently() (PR #35)
• Fixed Godoc of Collection.Query() method (PR #36)
• Fixed length of result slice (PR #38)
• Fixed filter test (PR #41)

Breaking changes

• Because functions can't be (de-)serialized, GetCollection requires a new parameter of type EmbeddingFunc, in order to set the correct func when using a DB with persistence and it just loaded the collections and documents from storage. (PR #25)
• Some methods now return an error (due to file operations when persistence is used)
• Additional validations will return an early error, but most (if not all) prior calls with the invalid parameters probably lead to some errors down the line anyway
• Collection.Metadata is not exported anymore
• Result.Document field was renamed to Result.Content, to avoid confusion with the now exported Document struct
