Code Review

This pull request introduces a new feature to output benchmark results to a JSON file. The implementation is a good start, but there are a few issues that need to be addressed. I've found a critical issue that could lead to a division-by-zero crash, and a high-severity bug that causes result data to be lost when running benchmarks in batches. Additionally, there are several medium-severity issues related to error handling during JSON object creation, which could lead to silent failures. The rest of the changes are minor stylistic fixes.

Code Review

This pull request adds a feature to write benchmark results to a JSON file. While the implementation for specified queries is correct, there's a critical issue in totalChildQuery that causes the JSON output file to be overwritten when running batch queries, leading to loss of results. Additionally, there's a minor issue with error handling when creating JSON objects.
