Class DynamoDB

Integration between the LaunchDarkly SDK and DynamoDB.

Inheritance

System.Object

DynamoDB

Namespace: LaunchDarkly.Sdk.Server.Integrations

Assembly: LaunchDarkly.ServerSdk.DynamoDB.dll

Syntax

public static class DynamoDB : Object

Fields

DataStorePartitionKey

Name of the partition key that the data store's table must have. You must specify this when you create the table. The key type must be String.

Declaration

public const string DataStorePartitionKey = "namespace"

Field Value

Type	Description
System.String

DataStoreSortKey

Name of the sort key that the data store's table must have. You must specify this when you create the table. The key type must be String.

Declaration

public const string DataStoreSortKey = "key"

Field Value

Type	Description
System.String

Methods

BigSegmentStore(String)

Returns a builder object for creating a DynamoDB-backed Big Segment store.

Declaration

public static DynamoDBStoreBuilder<IBigSegmentStore> BigSegmentStore(string tableName)

Parameters

Type	Name	Description
System.String	tableName	the DynamoDB table name; this table must already exist

Returns

Type	Description
DynamoDBStoreBuilder<LaunchDarkly.Sdk.Server.Subsystems.IBigSegmentStore>	a Big Segment store configuration object

Remarks

You can use methods of the builder to specify any non-default DynamoDB options you may want, before passing the builder to LaunchDarkly.Sdk.Server.Components.BigSegments(LaunchDarkly.Sdk.Server.Subsystems.IComponentConfigurer{LaunchDarkly.Sdk.Server.Subsystems.IBigSegmentStore}). In this example, the store is configured to use a table called "table2":

    var config = Configuration.Builder("sdk-key")
        .DataStore(
            Components.BigSegments(
                DynamoDB.BigSegmentStore("table2")
            )
        )
        .Build();

Note that the SDK also has its own options related to Big Segments that are configured at a different level, because they are independent of what database is being used. For instance, the builder returned by LaunchDarkly.Sdk.Server.Components.BigSegments(LaunchDarkly.Sdk.Server.Subsystems.IComponentConfigurer{LaunchDarkly.Sdk.Server.Subsystems.IBigSegmentStore}) has an option for the status polling interval:

    var config = Configuration.Builder("sdk-key")
        .DataStore(
            Components.BigSegments(
                DynamoDB.BigSegmentStore("table2")
            ).StatusPollInterval(TimeSpan.FromSeconds(30))
        )
        .Build();

DataStore(String)

Returns a builder object for creating a Redis-backed persistent data store.

Declaration

public static DynamoDBStoreBuilder<IPersistentDataStoreAsync> DataStore(string tableName)

Parameters

Type	Name	Description
System.String	tableName	the DynamoDB table name; this table must already exist

Returns

Type	Description
DynamoDBStoreBuilder<LaunchDarkly.Sdk.Server.Subsystems.IPersistentDataStoreAsync>	a data store configuration object

Remarks

This is for the main data store that holds feature flag data. To configure a Big Segment store, use BigSegmentStore(String) instead.

You can use methods of the builder to specify any non-default DynamoDB options you may want, before passing the builder to LaunchDarkly.Sdk.Server.Components.PersistentDataStore(LaunchDarkly.Sdk.Server.Subsystems.IComponentConfigurer{LaunchDarkly.Sdk.Server.Subsystems.IPersistentDataStoreAsync}). In this example, the store is configured to use a table called "table1":

    var config = Configuration.Builder("sdk-key")
        .DataStore(
            Components.PersistentDataStore(
                DynamoDB.DataStore("table1")
            )
        )
        .Build();

Note that the SDK also has its own options related to data storage that are configured at a different level, because they are independent of what database is being used. For instance, the builder returned by LaunchDarkly.Sdk.Server.Components.PersistentDataStore(LaunchDarkly.Sdk.Server.Subsystems.IComponentConfigurer{LaunchDarkly.Sdk.Server.Subsystems.IPersistentDataStoreAsync}) has options for caching:

    var config = Configuration.Builder("sdk-key")
        .DataStore(
            Components.PersistentDataStore(
                DynamoDB.DataStore("table1")
            ).CacheSeconds(15)
        )
        .Build();
