⚠ BREAKING CHANGES
  • esutil: default Client to elasticsearch.NewBase in NewBulkIndexer
  • esapi: params previously typed *int on ~25 esapi endpoints are now *int64 to match the spec long type. Call sites passing untyped integer literals keep compiling; call sites passing a typed int variable need an int64(...) cast.

v9.3.0

Compare Source

⚠ BREAKING CHANGES
  • Upgrade Go version from 1.23 to 1.24 (#​1137)
  • API: API methods and request fields that previously accepted a single string for resource identifiers (e.g., indices, names, IDs, routing, features) now require []string. Corresponding WithX helpers now accept variadic arguments (...string).
  • API: All ExpandWildcards request fields were changed from string to []string, and WithExpandWildcards helpers now accept variadic arguments (...string).
  • API: Routing parameters across document, search, and multi-document APIs were changed from string to []string, and related WithRouting helpers now accept variadic arguments (...string).
  • API: Duration-based parameters previously expressed as string now use time.Duration (e.g., KeepAlive, Interval, BucketSpan). Call sites must pass time.Duration values.
  • API: ML APIs using interface{} for start/end time parameters now require string values, removing support for arbitrary types.
  • API: Several top-level API methods now require []string instead of string for path parameters that support multiple resources (e.g., indices, templates, data streams, transforms, repositories, privileges).
  • API: MonitoringBulk was refactored: DocumentType support was removed, Interval is now time.Duration, and required parameters were added explicitly to the method signature.
  • API: Some WithX functional options changed between single-value and variadic forms to match API behaviour. Existing option usage may require updates.
  • API: Request struct fields were updated to reflect REST API semantics, including changes from string to []string and removal of deprecated fields. Direct struct initialization may require changes.
Features
  • API: Introduce strong typing for duration values (3c657da)
  • API: Support multi-value resource parameters (3c657da)
  • API: Support multiple resources per request (3c657da)
  • API: Update APIs to 9.3.0 (3c657da)
  • Expose FlushedMs metric in BulkIndexer (#​1191) (d67d0be)
  • Typed API: Add DenseVectorF32 and DenseVectorBytes types, improving indexing performance of dense vectors by up to 3x when used instead of a float32 array (f543b82)
  • Typed API: Update TypedAPI to latest elasticsearch-specification 9.3.0 (f543b82)
  • Upgrade Go version from 1.23 to 1.24 (#​1137) (05f15eb)
Bug Fixes
  • API: Align request structs with Elasticsearch REST spec (3c657da)
  • API: Align routing parameters with REST API (3c657da)
  • API: Correct functional option cardinality (3c657da)
  • API: Modernize MonitoringBulk API (3c657da)
  • API: Normalize expand_wildcards handling (3c657da)
  • API: Simplify ML time range parameters (3c657da)
  • esutil: Handle error from Seek in BulkIndexer.writeBody (#​1162) (ab7b3bb)
  • Typed API: Marshal Additional Properties into json.RawMessage instead of any to avoid loss of precision (#​1147) (e3e61d6)

API

  • Updated APIs to 9.1.0

Typed API

  • Update TypedAPI to latest elasticsearch-specification 9.1
  • This release introduces a new MethodAPI used by the TypedClient which makes the client friendlier for dead code elimination.
    Reducing the size of the client when only a subset of the APIs are used. The old API structure remains available for backward compatibility, but it is now deprecated.

  • The client now requires Go 1.23 or later.

New

  • This release introduces an optional package for the TypedAPI named esdsl.
    It provides a domain-specific language (DSL) for building Elasticsearch queries in Go.
    The DSL is designed to simplify query construction, making it easier to build complex queries without writing raw JSON.
