CPI data store entry limit

Hi all,

does anybody know whether data stores have a limit in its size? How many entries can I store within them? I need to undesrtand if I can design my flow relying on a data store to keep thousands of entries (with no content, just labels) or if there are technical limitations when reading such loads of info. I know using a db table would be ideal but I need to know if SAP relesed KBAs or official documentations on this subject.

Thanks.

Cristian
