------------------------------------
Summary: Improve performance of
FetchStatsLogger#logIndividualFetchComplete
Key: TEZ-3650
URL: https://issues.apache.org/jira/browse/TEZ-3650
Project: Apache Tez
Issue Type: Improvement
Reporter: Jonathan Eagles
Assignee: Jonathan Eagles
The cost of logging the fetch completed statement is dominated by two main
factors 1) Formatting the download rate and 2) Minor String concatenation that
isn't getting optimized.
In this jira I propose a new Formatter that is optimized by implementing the
StringBuilder#append(long) algorithm, but allows for formatting and reuse of
StringBuilder.
