> Currently OakCodec is used by default if full text indexing is enabled for that index.
OakCodec disables compression and was done as performance issues were observed around 1.0
release (See OAK-1737). 
> Post 1.0 we introduced CopyOnRead which should provide better performance even with compression
enabled. We should revisit the usage of OakCodec by default to see if with default code we
get comparable performance or not and hence get benefit of smaller index size.
> Changing the default would require change in index format version as this change would
not be compatible to default
> Note that one can still change codec by specifying {{codec}} value for index config to
the code name like {{Lucene46}}
