## Which issue does this PR close? Closes #9398 Closes #5347 ## Rationale for this change New contributors (myself included!) often run `cargo test` locally when setting up DataFusion for development and are surprised to see their system lock up or fail to complete the tests. This is due to very high memory requirements to complete the tests with default parallelism. See linked issues for more discussion on the cause of high memory usage. ## What changes are included in this PR? Documents this phenomenon in the contributors documentation page and suggests a workaround to run ```bash cargo test -- --test-threads 1 ``` if you run into memory limitations. ## Are these changes tested? No - just a doc update. ## Are there any user-facing changes? New contributor docs -- This is an automated message from the Apache Git Service.
