Hello everyone,

I just want to find out the behavior of the sincedb when using the read mode of the file input plugin.

As a matter of fact, I just want to confirm that the current read position is logged only after a file has been completely read.

Please is there a way of changing this behavior so as to make logstash write to this file at sincedb\_write\_interval seconds.

Thanks in advance
