Cache Key

[David LAGARDERE]

Hello.

I'm doing an extensive use of cache and I'd like
to be sure that every key is unique. Can the Hash
algorithm provided with Cocoon (buzhash) generate two
identical keys ? If so, what will happen ?

Thanks in advance

Cache Key Uniqueness

[David LAGARDERE]

Hello. 
I have read that BuzHash algorithm is more efficient
for keys whose length is lower than 64 bytes. Do I
have a strong probability of collision if my key is
greater than 64 bytes ? What about using String as
cache key ?

Thanks in advance.

The cache used to use String but switched after some discussion -
a primary reason was speed on cache lookups IIRC.  Do you
need more than 64 bytes? The key only has to be unique within
the scope of your component, not all components/cache items.
