OptionalmaxMaximum number of worker instances in the pool.
Security Recommendation: For production applications that accept user uploads, set this to a reasonable limit (e.g., 2-4) to prevent resource exhaustion attacks. Without limits, malicious users could spawn unlimited workers by uploading multiple large CSV files simultaneously, leading to memory exhaustion and DoS.
OptionalworkerCustom worker URL to use for all workers in the pool.
