Enum Constant Details

RETRY_REQUEST_WIN_COUNT

public static final FastClientMetricEntity RETRY_REQUEST_WIN_COUNT

Count of retry requests where the retry "won" (outperformed the original).

METADATA_STALENESS_DURATION

public static final FastClientMetricEntity METADATA_STALENESS_DURATION

Metadata staleness watermark reported asynchronously in milliseconds.

REQUEST_FANOUT_COUNT

public static final FastClientMetricEntity REQUEST_FANOUT_COUNT

Fanout size distribution for requests, with fanout type as a dimension.

REQUEST_REJECTION_COUNT

public static final FastClientMetricEntity REQUEST_REJECTION_COUNT

Count of requests rejected by the client.

REQUEST_REJECTION_RATIO

public static final FastClientMetricEntity REQUEST_REJECTION_RATIO

Ratio of requests rejected by the client to total requests. TODO: Evaluate if this metric can be implemented as a derived OTel metric and if so, migrate to that.

Method Details

values

public static FastClientMetricEntity[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static FastClientMetricEntity valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
