> [Java] Fix the performance degradation of integration tests
> -----------------------------------------------------------
>
> Key: ARROW-8940
> URL: https://issues.apache.org/jira/browse/ARROW-8940
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Java
> Reporter: Liya Fan
> Assignee: Liya Fan
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> In the past, we run integration tests from main methods, and recently, we
> have changed this to run them by the failsafe plugin.
> This is a good change, but it also leads to significant performance
> degradation. In the past, it took about 10s to run
> {{ITTestLargeVector#testLargeDecimalVector}}, now it takes more than half an
> hour.
> Our investigation shows that the problem was caused by calling
> {{HistoricalLog#recordEvent}} repeatedly. This method is called only when
> {{BaseAllocator#DEBUG}} is enabled. In a unit/integration test, the flag is
> enabled by default.
> We solve the problem with the following steps:
> 1. We set system property to disable the {{BaseAllocator#DEBUG}} flag.
> 2. We change the logic so that the system property takes precedence over the
> {{AssertionUtil#isAssertionsEnabled}} method.
> This makes the integration tests as fast as before.
