I'm more of a crafting player and my question is how many crafting recipes can I learn on one character?

Is there a limit to the number of crafting recipes I can learn on a character or learn, and if so, how many (exact number) of recipes can I learn, but isn't there a limit?

The number of professions you can become an expert / master in is limited, but afaik there's no limit to the number of recipies
