The Go SDK for Azure Cosmos DB is customizable using ClientOptions struct for configurations and retry policies.
Retry policies handle common scenarios like network errors, Forbidden, NotFound, and Service Unavailable.
Retriable errors like invalid account endpoints trigger retries with increasing delays.
Customizing retry policies with maximum retries and delays can be done using RetryOptions.
Fault injection policies allow simulating network errors for testing purposes.
Custom HTTP client configurations such as skipping certificate verification or adding custom headers are possible.
OpenTelemetry support enables distributed tracing with Azure services like Cosmos DB.
Query metrics like execution time, document counts, and sizes can be accessed for monitoring query performance.
The SDK's flexibility allows developers to tailor configurations for specific requirements and use cases.
Configuration options, retry policies, fault injection, tracing, and query metrics enhance the customization capabilities of the Azure Cosmos DB Go SDK.
