com.walmartlabs.lacinia.tracing — com.walmartlabs/lacinia 0.39-alpha-5

Support for tracing of requests, as per the Apollo tracing specification.

create-timing-start clj

(create-timing-start)

Captures the initial timing information that is used later to calculate offset from the start time (via offset-from-start).

duration clj

(duration start-offset)

Returns the number of nanoseconds since the start offset.

enable-tracing clj

(enable-tracing context)

Modifies the application context to enable tracing.

Tracing can signficantly slow down execution of the query document, both because of the essential overhead, and because certain optimizations are disabled during a traced request.

inject-tracing clj

(inject-tracing result
                timing-start
                parse-phase
                validation-phase
                resolver-timings)

Injects the tracing data into result map, under :extensions.

offset-from-start clj

(offset-from-start timing-start)

Given the initial timing information from create-timing-start, calculates the start offset for an operation, as a number of nanoseconds.

timestamp clj

(timestamp)

Returns the current time as a RFC-3339 string.
