Subject RE: Did the default page size change between Ignite 2.2 and 2.3
Date Sun, 03 Dec 2017 01:53:09 GMT
BTW, is there a way of determining what the page size of a persistent store
is before opening it?

Thanks Denis.



I did give that a try in the meantime and it sorted it out.



Do you know how much of a performance delta it made?



Thanks,

Raymond.

The page default size was changed to 4KB in 2.3 because of performance
considerations:

Roll the size back to 2KB manually in your cluster configuration to get rid
off this exception.

I am upgrading from Ignite 2.2 to 2.3. I use persistent storage and have an
existing data store.



When activating the cluster I get the following error in the C# client:



class org.apache.ignite.IgniteCheckedException: Failed to verify store file
(invalid page size) [expectedPageSize=4096, filePageSize=2048]



I didn’t set a specific page size in 2.2 or 2.3.



Did this change?



Thanks,

Raymond.
