cassandra: Add option to select (hopefully) more efficient batch insertion algos · fc950deb

vlorentz authored 3 years ago

This adds a new config option for the cassandra backend,

* 'one-per-one' is the default, and preserves the current naive behavior
* 'concurrent' and 'batch' are attempts at being more efficient
