Hi

Are their size limitations in terms of columns and rows for DMN Tables for both 1) DMN Engine and 2) Modeller?

Thanks

Hi @dre,

there are basically no limitations.
However, you should keep in mind that a big table can be hard to read and maintain.

Hi, how much performance impact will be while evaluation or will there be any performance/memory issues on the system. The table might contain more than 100,000 rows. Columns size might be not more than 10.

Hi @sagu,

that is hard to predict. But you can run a benchmark to test it. Have a look at https://blog.camunda.com/post/2015/12/dmn-benchmark/.

However, you should think twice if you want to have a decision table with > 100.000 rows. Maybe, there is a more efficient way to evaluate it.

Best regards,
Philipp
