This parameter sets the minimum size of sensor event log to cache before sending to the server.
10 * 1024 * 1024
This is a numeric setting that can accept any valid Python math expression (see default). It designates a size in bytes; therefore, "10 * 1024 * 1024" means 10 MB.
Pushed to 6.x sensor in check-in response. Used in legacy throttle calculation during check-in to compare size of legacy sensor backlog.
