RE: max size of Ignite cache (not memory size, i mean max amount ofrecords)

Hi Jeff,

I believe its Long.MAX_VALUE, so I wouldn’t worry about reaching that cap in one’s lifetime :)

Thanks,
Stan

hi Igniter,

Is there a max limit for the amount of records in one cache? (is it
Integer.MAX_VALUE?)
what will happen when a cache reaches the max limit and we keep adding data
into it?


Thanks,
Jeff

I'd add that size methods of CacheDataStore (abstraction which is 
responsible for storing partition data in offheap) actually return int 
type. That means that there's a limit of Integer.MAX_VALUE entries per 
partition, which is still huge.
FYI: If total cache size is greater than Integer.MAX_VALUE, you can use 
IgniteCache#sizeLong method in order to obtain correct size.
