Closeable

public final class CosmosAsyncClient
implements Closeable

Provides a client-side logical representation of the Azure Cosmos DB service. This asynchronous client is used to configure and execute requests against the service.

CosmosAsyncClient is thread-safe. It's recommended to maintain a single instance of CosmosAsyncClient per lifetime of the application which enables efficient connection management and performance. CosmosAsyncClient initialization is a heavy operation - don't use initialization CosmosAsyncClient instances as credentials or network connectivity validations.

createDatabase

public Mono createDatabase(CosmosDatabaseProperties databaseProperties)

Creates a database. After subscription the operation will be performed. The Mono upon successful completion will contain a single resource response with the created database. In case of failure the Mono will error.

Parameters:

databaseProperties - CosmosDatabaseProperties.

Returns:

an Mono containing the single cosmos database response with the created database or an error.

createDatabase

public Mono createDatabase(CosmosDatabaseProperties databaseProperties, CosmosDatabaseRequestOptions options)

Creates a database. After subscription the operation will be performed. The Mono upon successful completion will contain a single resource response with the created database. In case of failure the Mono will error.

Parameters:

databaseProperties - CosmosDatabaseProperties.

Returns:

an Mono containing the single cosmos database response with the created database or an error.

createDatabase

public Mono createDatabase(CosmosDatabaseProperties databaseProperties, ThroughputProperties throughputProperties)

Creates a database. After subscription the operation will be performed. The Mono upon successful completion will contain a single resource response with the created database. In case of failure the Mono will error.

Parameters:

databaseProperties - CosmosDatabaseProperties.
throughputProperties - the throughput properties for the database.

Returns:

an Mono containing the single cosmos database response with the created database or an error.

createDatabase

public Mono createDatabase(CosmosDatabaseProperties databaseProperties, ThroughputProperties throughputProperties, CosmosDatabaseRequestOptions options)

Creates a database. After subscription the operation will be performed. The Mono upon successful completion will contain a single resource response with the created database. In case of failure the Mono will error.

Parameters:

databaseProperties - CosmosDatabaseProperties.
throughputProperties - the throughput properties for the database.

Returns:

an Mono containing the single cosmos database response with the created database or an error.

createDatabase

public Mono createDatabase(String id)

Creates a database. After subscription the operation will be performed. The Mono upon successful completion will contain a single resource response with the created database. In case of failure the Mono will error.

Parameters:

id - id of the database.

Returns:

a Mono containing the single cosmos database response with the created database or an error.

createDatabase

public Mono createDatabase(String id, ThroughputProperties throughputProperties)

Creates a database.

Parameters:

id - the id.
throughputProperties - the throughputProperties.

Returns:

the mono.

createDatabaseIfNotExists

public Mono createDatabaseIfNotExists(CosmosDatabaseProperties databaseProperties)

CREATE a Database if it does not already exist on the service. The Mono upon successful completion will contain a single cosmos database response with the created or existing database.

Parameters:

databaseProperties - CosmosDatabaseProperties.

Returns:

a Mono containing the cosmos database response with the created or existing database or an error.

createDatabaseIfNotExists

public Mono createDatabaseIfNotExists(String id)

Create a Database if it does not already exist on the service. The Mono upon successful completion will contain a single cosmos database response with the created or existing database.

Parameters:

id - the id of the database.

Returns:

a Mono containing the cosmos database response with the created or existing database or an error.

createDatabaseIfNotExists

public Mono createDatabaseIfNotExists(String id, ThroughputProperties throughputProperties)

Create a Database if it does not already exist on the service. The throughputProperties will only be used if the specified database does not exist and therefor a new database will be created with throughputProperties. The Mono upon successful completion will contain a single cosmos database response with the created or existing database.

Parameters:

id - the id.
throughputProperties - the throughputProperties.

Returns:

the mono.

createGlobalThroughputControlConfigBuilder
