file length and configuring metadata

[kate88]

Hi!

I use sth like that:

GridFile.Metadata meta = metadata.get(fileName);

meta.getLength();

But the result is not good for me becouse method getLength() doesn't return real file size but CHUNK_SIZE*chunkCount..

Is it possible to get real file length from metadata?

And question 2:

Is it possible to configure metada and add some extra information to it?

You should use GridFile.length(), which overrides the JDK's File.length().  Internally, this uses metadata stored about the actual file length.

And question 2:

What arbitrary info do you wish to store here?  Is it something generically useful that we have missed?

Thanks Manik!

So I am making some kind of filesystem based on infinispan and I need to store some extra information which would be useful only in my system.  Is it possible to store some extra information in metadata?

Nope.  Perhaps just use an additional file for this metadata?

so is it possible to replicate only one file while other are distributed?

Nope.  You'd need to use separate caches for this.
