Summary: wrap FileWriter with BufferedWriter for better performance
Key: FLINK-12187
URL: https://issues.apache.org/jira/browse/FLINK-12187
Project: Flink
Issue Type: Bug
Reporter: bd2019us
Location:
src/main/java/org/apache/flink/examples/java/relational/util/WebLogDataGenerator.java
The FileWriter.write() method is invoked multiple times in loops, which is bad
to the performance of program. The decorator class BufferedWriter can be used
to alleviate the impact of frequent IO operation with caches. Therefore, when
the write() method is intensively used, the BufferedWriter is highly
recommended and should be preferred.
