Well, he's still suggesting we switch to tab as delimiter in sources. Same solution,
but with the extra bonus of allowing udp-filter to give our downstream consumers what they
currently expect.

Hi Erik,
Yes it is downwards compatible but does not outweigh the drawbacks. It's not simple,
as it creates a disconnect between the configuration of the server log and the actual
output. In addition, it is not a future proof solution because we also want to stream the
server log data to the analytics cluster and then we will be still stuck with the same
problem (as streaming the data into the analytics cluster will not depend on the
udp-filter software). We should apply a real solution not a monkey patch.

There are more suggestions hanging in the air waiting to be shot down.
Character replacement in c is very cheap.
So why not feed Diederik's filter with tab delimited data, and export space delimited
data?
The filter first replaces all (non delimiting) spaces by underscores, then replaces all
(delimiting) tabs by spaces.
Simple, and downwards compatible.

Subject: Re: [Analytics] Using tab as delimiter instead of space in the log files
So far nobody has responded to my inquiry on whether they would be affected by this
chance. So please let us know if you are consuming a server log and you are expecting
spaces as delimiters. We want to make sure that we are aware of all the people that will
be affected by this.
Best,
Diederik
