Is there any cap on Go's built-in map or slice? I know slice can have cap
but what is the maximum number of elements that we can have in one map and
slice?

I am thinking about having my entries in Redis or other key-value storage
until I have too many entries to store in memory.

Any advice will be appreciated. Thanks!

The length and capacity of slices and maps are ints, so I believe that
the int size on your platform (as well as available memory, of course)
are the only limitations.

There is no limit the number of elements you can store in a map save the
limitations of your hardware or the current maximum size of the heap.
