Namespace:

Microsoft.Azure.Documents.Partitioning

Packages:

Microsoft.Azure.DocumentDB v2.18.0, Microsoft.Azure.DocumentDB.Core v2.18.0

Overloads

HashPartitionResolver(Func<Object,String>, IEnumerable<String>, Int32, IHashGenerator)	Initializes a new instance of the HashPartitionResolver in the Azure Cosmos DB service using the specified partitionKeyExtractor value.
HashPartitionResolver(String, IEnumerable<String>, Int32, IHashGenerator)	Initializes a new instance of the HashPartitionResolver in the Azure Cosmos DB service using the specified partitionKeyPropertyName value.

HashPartitionResolver(Func<Object,String>, IEnumerable<String>, Int32, IHashGenerator)

Initializes a new instance of the HashPartitionResolver in the Azure Cosmos DB service using the specified partitionKeyExtractor value.

public HashPartitionResolver (Func<object,string> partitionKeyExtractor, System.Collections.Generic.IEnumerable<string> collectionLinks, int numberOfVirtualNodesPerCollection = 128, Microsoft.Azure.Documents.Partitioning.IHashGenerator hashGenerator = default);

new Microsoft.Azure.Documents.Partitioning.HashPartitionResolver : Func<obj, string> * seq<string> * int * Microsoft.Azure.Documents.Partitioning.IHashGenerator -> Microsoft.Azure.Documents.Partitioning.HashPartitionResolver

Public Sub New (partitionKeyExtractor As Func(Of Object, String), collectionLinks As IEnumerable(Of String), Optional numberOfVirtualNodesPerCollection As Integer = 128, Optional hashGenerator As IHashGenerator = Nothing)

Parameters

partitionKeyExtractor

Func<Object,String>

A function to extract the partitionKey from the document

collectionLinks

IEnumerable<String>

The list of collection links used for hashing.

numberOfVirtualNodesPerCollection

Int32

The number of virtual nodes per collection in the conisistent hash ring.

hashGenerator

IHashGenerator

The IHashGenerator to use in consistent hashing. If null, the default MD5 hash generator is used.

HashPartitionResolver(String, IEnumerable<String>, Int32, IHashGenerator)

Initializes a new instance of the HashPartitionResolver in the Azure Cosmos DB service using the specified partitionKeyPropertyName value.

public HashPartitionResolver (string partitionKeyPropertyName, System.Collections.Generic.IEnumerable<string> collectionLinks, int numberOfVirtualNodesPerCollection = 128, Microsoft.Azure.Documents.Partitioning.IHashGenerator hashGenerator = default);

new Microsoft.Azure.Documents.Partitioning.HashPartitionResolver : string * seq<string> * int * Microsoft.Azure.Documents.Partitioning.IHashGenerator -> Microsoft.Azure.Documents.Partitioning.HashPartitionResolver

Public Sub New (partitionKeyPropertyName As String, collectionLinks As IEnumerable(Of String), Optional numberOfVirtualNodesPerCollection As Integer = 128, Optional hashGenerator As IHashGenerator = Nothing)

Parameters

partitionKeyPropertyName

String

The name of the property in the document to execute the hashing on.

collectionLinks

IEnumerable<String>

The list of collection links used for hashing.

numberOfVirtualNodesPerCollection

Int32

The number of virtual nodes per collection in the conisistent hash ring.

hashGenerator

IHashGenerator

The IHashGenerator to use in consistent hashing. If null, the default MD5 hash generator is used.

Remarks

Use when you want to partition based on a single property name. For other partitioning schemes, use the constructor with partitionKeyExtractor instead.
