Overview

Data structure for storing the counts and timings of a transaction. Note that the start and end times are monotonic time and not wall clock time.

This structure deliberately does not hold the queries executed within the transaction so that retaining it for the duration of a count_queries block stays cheap. The full query details are only available transiently in the transaction_time notification payload (see TransactionDetails).
