Method Detail

getTraces

public com.google.common.util.concurrent.ListenableFuture<List<List<Span>>> getTraces(QueryRequest request)

This fans out into a potentially large amount of requests related to the amount of annotations queried. The returned future will fail if any of the inputs fail.

When service name is unset, service names will be fetched eagerly, implying an additional query.

getRawTrace

Since the schema doesn't have a unique index on Span.traceIdHigh, we have to filter client-side.
