Summary: Initialize StringBuilder in Slf4jReporter with estimated size Key: FLINK-10082 URL: https://issues.apache.org/jira/browse/FLINK-10082 Project: Flink Issue Type: Improvement Components: Metrics Affects Versions: 1.5.2, 1.6.0 Reporter: Chesnay Schepler Assignee: Chesnay Schepler The {{Slf4jReporter}} uses a StringBuilder to generate the report that is later logged. Currently we don't pass the initial size, which for large deployments can result in frequent resizing of the backing array. We could either estimate the expected size based on the # of metrics, or store the size of the last report (given that the total metrics space is fairly constant). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
