Great thats the point with it. Its actually used by eg camel-jms if you set option transferExchange=true > I made a first test.

But they would most often be that. I would actually state its a fair requirement that the correlation keys are String based as well. Then you can use VARCHAR for those keys which makes it easy to query the database. > Did I miss something here or is it really HawtDB related ? > I suppose there is a reason why the index are parametrized with > <Buffer,Buffer> and not <String,Buffer>. > HawtDB is a storing all its data as byte streams, hence it uses a Buffer abstraction.
