azure_cosmosdb 2.1.1

Connector for Azure Cosmos DB on Dart and Flutter platforms. Supports Cosmos DB SQL API, indexing policies, users, permissions, and spatial types.

2.1.1

• Upgrade version of http.

2.1.0

• Enable support for Dart 3.

2.0.2

• Upgrade version of murmur3.

2.0.1

• Improved documentation & tests.
• Retry batch operations failing with a 429 "Too many requests" status.

2.0.0

• Added [PartitionKeySpec] for partition key definition. A [PartitionKeySpec] must be provided when creating a [CosmosDbContainer]. The static final instance [PartitionKeySpec.id] can be used as the default partition key ['/id']. When opening an existing collection, the [PartitionKeySpec] is loaded from the Cosmos DB response. [PartitionKeySpec.from] extracts the partition key from a [BaseDocument] according to the partition key definition.
• Support for multiple paths in [PartitionKeySpec] is available, in which case the [CosmosDbServer] connection must be initialized with preview: true.
• Added [PartitionKey] for providing a partition key when operating on documents/queries. The special value [PartitionKey.all] enables cross-partition queries.
• Added [TransactionalBatch] and [CrossPartionBatch] for batch processing.
• Please note that support for batch and multi-partition key are still experimental.
• Breaking changes - several classes have been renamed e.g. [CosmosDbCollection] --> [CosmosDbContainer], APIs dealing with bare String partition keys now use [PartitionKey]/[PartitionKeySpec], etc.

1.8.1

• _client.dart: return early with null upon a "204 - No Content" status code (fix for https://github.com/d-markey/azure_cosmosdb/issues/1). Also skip parsing the response body if content-length is zero.

1.8.0

• Added support for patching documents. A document may be patched conditionally and the condition can be parameterized (parameter values are integrated into the condition client-side, as Cosmos DB does not accept parameterized conditions out-of-the-box). Variable names MUST start with @.
• Added CosmosDbCollection.get() to retrieve the latest version of a document. When the document has mixin EtagMixin, the value of the _etag field is sent to Cosmos DB in the If-None-Match header (causing a response with HTTP status code 304 "Not modified", in which case the document is returned as is).
• Added optional document parameter for CosmosDbCollection.delete(). When provided, the document attributes takes over the id value. The id parameter is deprecated and will eventually be removed.
• Added optional checkEtag parameter (default value: true) for CosmosDbCollection.delete() and CosmosDbCollection.replace(). When the document has mixin EtagMixin and checkEtag is true, the value of the _etag field is sent to Cosmos DB in the If-Match header. If the document has been updated in the meantime, a PreconditionFailureException exception will be thrown because the _etag field's value will have changed in Cosmos DB (causing a response with HTTP status code 412 "Precondition failure").
• Added PartitionKey field on CosmosDbCollection and marked PartitionKeys as obsolete. Use PartitionKey instead.
• Added PartitionKeyMixin to support custom partition keys in documents.
• Added support for throttling requests when Cosmos DB replies with HTTP status code 429 "Too many requests".

1.6.1

• Update README.md
• Added support for throughput when creating a database or a collection.

1.6.0

• Renamed Line class to LineString.
• Fix various issues in GeoJSON serialization (lat/long order in the JSON-array, serialization/deserialization...).
• Added unit tests to validate the spatial data sets used in tests.
• Added unit tests for spatial queries.

1.5.0

• Supports bounding box in spatial indexes.
• New class Point to represent spatial positions.
  • 2D/3D euclidean coordinates (aka geometry).
  • Latitude/longitude/optional altitude coordinates (aka geography).
• New classes to represent shapes supported by CosmosDB: Line, Polygon, MultiPolygon.
• Distance calculators for both geometrical (euclidean) and geographical (latitude/longitude) shapes.
  • Comes with a geographical distance calculator preconfigured with the Earth's radius in kilometers.
• Renamed Exception class to CosmosDbException (could be a breaking change).
• Most base classes ClassName have also been renamed to CosmosDbClassName.
  • This should eliminate the need for aliasing the Cosmos DB library while avoiding name collisions in your app. E.g. names for User, Collection, ... were too generic and could cause conflict with your code or other libraries.
  • This should not be a breaking change as previous names are still available, yet deprecated. They will be removed in a future version.
• Removed DebugHttpClient from the mainstream azure_cosmosdb library (could be a breaking change).
  • The debug HTTP client can still be used by importing azure_cosmosdb_debug instead.
• Test cases have been updated accordingly, and enriched to cover indexing policies and geometrical/geographical shapes.

• Document base classes: BaseDocument, BaseDocumentWithEtag
• Support for SQL query
• Unit tests & code coverage (currently limited to Server, Databases and Collections)
