Detailed Description

Declarations for client-side plugins of type MYSQL_CLIENT_TELEMETRY_PLUGIN.

Typedef Documentation

telemetry_end_span_t

typedef void(* telemetry_end_span_t) (telemetry_span_t *span)

End an OpenTelemetry trace span.

Parameters

[in]

span

Span to end

telemetry_injector_t

typedef void(* telemetry_injector_t) (telemetry_span_t *span, void *carrier_data, telemetry_text_map_carrier_set_t carrier)

Inject an OpenTelemetry trace context into an arbitrary text map carrier.

Parameters

[in]	span	The trace span to inject
[in]	carrier_data	text map carrier to set
[in]	carrier	Function to use to set the data in the carrier

telemetry_start_span_t

typedef telemetry_span_t *(* telemetry_start_span_t) (const char *name)

Start an OpenTelemetry trace span.

Parameters

[in]

name

span name

telemetry_text_map_carrier_set_t

typedef void(* telemetry_text_map_carrier_set_t) (void *carrier_data, const char *key, size_t key_length, const char *value, size_t value_length)

Abstract text map carrier set interface.

This is used for propagation, to set a key / value pair inside an arbitrary carrier.

Parameters

carrier_data	Opaque carrier data to set
key	Key to set
key_length	Length of key
value	Value to set
value_length	Length of value

client_telemetry_plugin

struct st_mysql_client_plugin_TELEMETRY* client_telemetry_plugin

extern

The global telemetry_plugin pointer.
