Generate 25k Rows

This example generates 1k Accounts with 4k Invoices & 20k InvoiceItems

This example demonstrates generating 1000 Account records, each with 0-4 Invoices, and each Invoice with 1-8 InvoiceItems. It highlights the ability to efficiently handle complex nested data with large volumes.

The controller pre-generates 20,000 InvoiceItems and 4000 Invoices. These cached lists are accessed via Funcs.GetCacheItemsRandom() and Funcs.GetCacheItemsNext() to retrieve random or sequential items. Random retrieval is slower—about 150% longer—due to shuffling overhead.

Item count is controlled by min/max parameters; setting both equal ensures a fixed number. Items are removed from the cache by default unless remove = false. If the cache runs out of items, the method fails silently, so estimating row counts beforehand is recommended.

Generating 25,000 rows took 618 ms.

The code also includes an example of extracting the GetInvoices() rule into an external function, which applies logic to match Invoice.AccountId with its parent AccountId, aiding both organization and debugging.
