I'm starting the buffer_server with

rosrun tf2_ros buffer_server

I've seen in its source code on github that one can specify the buffer size through the parameter server.

My questions are: in which measurement unit is the buffer_size parameter, what happens when the buffer is overfilled and is the buffer size the same as the duration after which the transform times out?

Thanks.

The buffer size is in seconds. It is how long data will be stored before being removed from the buffer. Roughly this means that you cannot query for data older than that parameter.
