Is there any limitation on the amount of registration I can use in a transaction with the Zend Framework?

Good Morning

Is there any limitation on the amount of registration I can use in a transaction with the Zend Framework? Example:

I’m trying to make an export of data from one database to another, has a table that has more than 100,000 records, apparently only importing 1000 (0 through 9999), I use a merge to do this export.

Thankful:
