Enhancement/Query: can we read continuously from file.

[GoogleCodeExporter]

Can we read continuously from file, i.e got notification that new index added 
in file. 

I want to implement it for DB and streaming, Is it possible?

I am not sure I understood the question. The reading will stop when the end of 
the file is reached. If a writer (max one per file) appends to the end of the 
file, reading it again will yield more data. Is this what you meant? Or are you 
talking more in terms of observer-like approach and waiting for the data to 
become available?

Sorry for bad explanation,
Yes I am looking for observer like approach. 
I want to use it in my academic project where I am collecting data from various 
node(which will be writer) and at front end(multiple instances), I want to 
display this data on a chart on continuous and real time basis like a stream.
Here front end will request data and chart will be plotted with available data 
and if new data comes then automatically chart got updated.
