Code Review

This pull request updates the configuration parser to allow rows_per_table to be set to 0 (previously it had to be positive or -1) and adds corresponding unit tests. The reviewer suggests automatically disabling the data cache when rows_per_table is set to 0 to prevent potential division-by-zero errors or undefined behavior in the caching logic, and recommends adding a test assertion to verify this automatic disabling.

Pull request overview

Expands GenerationConfig YAML parsing to accept rows_per_table: 0, enabling subtables to be created without any rows inserted. Previously only positive values or -1 (unlimited) were allowed.

Changes:

• Relax validation in ConfigParser so rows_per_table == 0 is accepted; update the error message accordingly.
• Add three parser tests covering rows_per_table values 0, -1, and -2 (invalid).
