Subject Re: a question storefileIndexSize

Stack, Thanks for your reply.
block size is default.
My Key length is 26 bytes and value is 300~400 bytes.
Is it big keys and small values ?

What Ted says or you could change the hfile block size; currently its
64k.  Make it bigger?  Do you have big keys and small values?   If so,
can you make do with smaller keys?  That would help with index size
too.
