Introducing record boundaries about bson4jackson HOT 3 CLOSED

I'm not sure what you mean by "records". Can you please give me more information about what you want to do? Thanks.

I need to create a log on disk of operations performed on an in-memory data structure. Each operation corresponds to one top-level json object. Currently, I'm just writing it all to files in json format. If the power goes out in mid-write, the results will not be pretty. I want to save space by using bson (there are logs of floating point numbers), and I want to switch from writing a text file to writing records to a BDB database, which will give me some recoverability. The simple thing to do would be to create a new generator for each record, take the bytes in a ByteArrayInputStream, and shove them to the database. That might not really be awful, but I wondered if I had other options.

Thank you for your explanation. Now I understand better what you are going to do.

As far as I remember, generator objects cannot be reused. There is no way of changing the output stream once the generator has been created.

Creating a new generator is a very lightweight operation. So, in fact it should not be a problem.
