question about buffer and log [need your help]

[z1q1q7]

I'm researching on influxdb-relay, now i have two questions:

1. will buffer request send to all http backends?
2. where does relay log's default position, or can i set it in config file?

Just for failing one. Each backend has its own buffer. https://github.com/influxdata/influxdb-relay#buffering
