class CosmosDiagnostics {}

* This is a Cosmos Diagnostic type that holds collected diagnostic information during a client operations. ie. Item.read(), Container.create(). It has three members - 1. clientSideRequestStatistics member contains aggregate diagnostic information, including - - metadata lookups. Here all the server requests, apart from the final intended resource are considered as metadata calls. i.e. for item.read(id), if the client makes server call to discover endpoints it would be considered as metadata call. - retries - endpoints contacted. - request, response payload stats. - gatewayStatistics - Information corresponding to main operation. For example during Item.read(), the client might perform many operations i.e. metadata lookup etc, but gatewayStatistics represents the diagnostics information for actual read operation.
2. diagnosticNode - Is a tree like structure which captures detailed diagnostic information. By default it is disabled, and is intended to be used only for debugging on non production environments. The kind of details captured in diagnosticNode is controlled by CosmosDbDiagnosticLevel. - CosmosDbDiagnosticLevel.info - Is default value. In this level only clientSideRequestStatistics are captured. Is is meant for production environments. - CosmosDbDiagnosticLevel.debug - Captures diagnosticNode and clientConfig. No request and response payloads are captured. Is not meant to be used in production environment. - CosmosDbDiagnosticLevel.debug-unsafe - In addition to data captured in CosmosDbDiagnosticLevel.debug, also captures request and response payloads. Is not meant to be used in production environment. 3. clientConfig - Captures information related to how client was configured during initialization.

Parameter options
Use to set options like response page size, continuation tokens, etc.
Example 1
import { CosmosClient } from "@azure/cosmos"; const endpoint = "https://your-account.documents.azure.com"; const key = "<database account masterkey>"; const client = new CosmosClient({ endpoint, key }); const { resource: databaseDefinition, database } = await client.databases.create({ id: "<name here>", });

If you're using TypeScript, you can use the following polyfill as long as you target ES6 or higher and are running on Node 6 or higher.

if (!Symbol || !Symbol.asyncIterator) {
  (Symbol as any).asyncIterator = Symbol.for("Symbol.asyncIterator");
}

Example 1

};

Conditions Associated with the request.

property allowUnboundedNonStreamingQueries

allowUnboundedNonStreamingQueries?: boolean;

Valid only for non streaming order by query. Default: false; When set to true, it allows queries to bypass the default behavior that blocks nonStreaming queries without top or limit clauses.

property bufferItems

bufferItems?: boolean;

Enable buffering additional items during queries. Default: false
This will buffer an additional page at a time (multiplied by maxDegreeOfParallelism) from the server in the background. This improves latency by fetching pages before they are needed by the client. If you're draining all of the results from the server, like .fetchAll, you should usually enable this. If you're only fetching one page at a time via continuation token, you should avoid this. If you're draining more than one page, but not the entire result set, it may help improve latency, but it will increase the total amount of RU/s use to serve the entire query (as some pages will be fetched more than once).

property continuation

continuation?: string;

Opaque token for continuing the enumeration. Default: undefined
Deprecated
Use continuationToken instead.

property continuationToken

continuationToken?: string;

Opaque token for continuing the enumeration. Default: undefined

property continuationTokenLimitInKB

continuationTokenLimitInKB?: number;

Limits the size of the continuation token in the response. Default: undefined
Continuation Tokens contain optional data that can be removed from the serialization before writing it out to a header. By default we are capping this to 1kb to avoid long headers (Node.js has a global header size limit). A user may set this field to allow for longer headers, which can help the backend optimize query execution."

property disableHybridSearchQueryPlanOptimization

disableHybridSearchQueryPlanOptimization?: boolean;

Default: false. If set to true, it disables the hybrid search query plan optimization. This optimization is enabled by default and is used to improve the performance of hybrid search queries.

property disableNonStreamingOrderByQuery

disableNonStreamingOrderByQuery?: boolean;

Disable the nonStreamingOrderBy query feature in supported query features. Default: false. Set to true to avoid error from an old gateway that doesn't support this feature.

property enableQueryControl

enableQueryControl?: boolean;

Controls query execution behavior. Default: false. If set to false, the query will retry until results are ready and maxItemCount is reached, which can take time for large partitions with relatively small data. If set to true, scans partitions up to maxDegreeOfParallelism, adds results to the buffer, and returns what is available. If results are not ready, it returns an empty response.

property enableScanInQuery

enableScanInQuery?: boolean;

Allow scan on the queries which couldn't be served as indexing was opted out on the requested paths. Default: false
In general, it is best to avoid using this setting. Scans are relatively expensive and take a long time to serve.

property forceQueryPlan

forceQueryPlan?: boolean;

This setting forces the query to use a query plan. Default: false
Note: this will disable continuation token support, even for single partition queries.
For queries like aggregates and most cross partition queries, this happens anyway. However, since the library doesn't know what type of query it is until we get back the first response, some optimization can't happen until later.
If this setting is enabled, it will force query plan for the query, which will save some network requests and ensure parallelism can happen. Useful for when you know you're doing cross-partition or aggregate queries.

property maxDegreeOfParallelism

maxDegreeOfParallelism?: number;

The maximum number of concurrent operations that run client side during parallel query execution in the Azure Cosmos DB database service. Negative values make the system automatically decides the number of concurrent operations to run. Default: 0 (no parallelism)

property maxItemCount

maxItemCount?: number;

Max number of items to be returned in the enumeration operation. Default: undefined (server will defined payload)
Expirimenting with this value can usually result in the biggest performance changes to the query.
The smaller the item count, the faster the first result will be delivered (for non-aggregates). For larger amounts, it will take longer to serve the request, but you'll usually get better throughput for large queries (i.e. if you need 1000 items before you can do any other actions, set maxItemCount to 1000. If you can start doing work after the first 100, set maxItemCount to 100.)

property partitionKey

partitionKey?: PartitionKey;

Limits the query to a specific partition key. Default: undefined
Scoping a query to a single partition can be accomplished two ways:
container.items.query('SELECT * from c', { partitionKey: "foo" }).toArray() container.items.query('SELECT * from c WHERE c.yourPartitionKey = "foo"').toArray()
The former is useful when the query body is out of your control but you still want to restrict it to a single partition. Example: an end user specified query.

property populateIndexMetrics

populateIndexMetrics?: boolean;

Enable returning index metrics in response headers. Default: false

property populateQueryMetrics

populateQueryMetrics?: boolean;

Enable returning query metrics in response headers. Default: false
Used for debugging slow or expensive queries. Also increases response size and if you're using a low max header size in Node.js, you can run into issues faster.

property useIncrementalFeed

useIncrementalFeed?: boolean;

Note: consider using changeFeed instead.
Indicates a change feed request. Must be set to "Incremental feed", or omitted otherwise. Default: false

Plugins allow you to customize the behavior of the SDk with additional logging, retry, or additional functionality.
A plugin is a function which returns a Promise<Response<T>>, and is passed a RequestContext and Next object.
Next is a function which takes in requestContext returns a promise. You must await/then that promise which will contain the response from further plugins, allowing you to log those results or handle errors.
RequestContext is an object which controls what operation is happening, against which endpoint, and more. Modifying this and passing it along via next is how you modify future SDK behavior.
