" Now streaming is very efficient rarely fails and there is no need to do it this way anymore"
I guess it's true in v1.2. Is it true also in v1.1 ? Thanks.

Now streaming is very efficient rarely fails and there is no need to do it this way anymore. This recipe will be abolished from the second edition. It still likely works except when using counters.

It's about splitting in 2 parts each token range taken in charge, after the split, with 2 nodes: the existing one, and a new one. And for starting a new node, one needs to: - copy the data records from the corresponding node (without the "system" records) - start the new node with "auto_bootstrap: false" This raises 2 questions: A) is this recipe still valid with v1.1 and v1.2 ? B) do we still need to start the new node with "auto_bootstrap: false" ? My guess is "yes" as the happening of the bootstrap phase is not recorded into the data records. Thanks.
