[jira] [Created] (FLINK-27035) Reduce memory usage of ByteArrayWrapperSerializerTest

Chesnay Schepler created FLINK-27035:
----------------------------------------

             Summary: Reduce memory usage of ByteArrayWrapperSerializerTest
                 Key: FLINK-27035
                 URL: https://issues.apache.org/jira/browse/FLINK-27035
             Project: Flink
          Issue Type: Technical Debt
          Components: API / Python, Tests
            Reporter: Chesnay Schepler
             Fix For: 1.16.0


The ByteArrayWrapperSerializerTest can consume up to 1gb of heap space on it's own.
This is due to the parallelization in SerializerTestBase#testDuplicate running tests 10x in parallel, the test data being duplicate twice, and the test using 32mb arrays.
