java - When using field grouping in storm, is there a limit to known field values or a timeout? -

-

i use field grouping apache storm, works well.

but if have infinite number of field values, means storm has keep track of infinite number of values in bolts! otherwise, values go wrong bolt , destroy caching technique.

i suppose there cache somewhere in bolt expiration system or/and limitation on number of field values check bolt field grouping. possible tune / overwrite it?

you don't need cache nothing, fieldsgrouping uses mod hash function determine task send tuple, can sure processed in correct task.
