I seem to keep seeing the following in the ns-server logs without any results in the tap.py output.

[CODE]Backfilling token for eq_tapq: went invalid. Stopping backfill.[/CODE]

tap.py output just shows the following:

[CODE]info: New bin connection from None[/CODE]

Can you send the command-line that you are running tap.py with?

Thanks

Perry

Yeah, we obviously need to document this a bit better. Right now it's kind of an internal tool that isn't designed to be exposed to the user. We'll be wrapping a much better interface around it over time, but to get you up and running:
./tap.py localhost:11210

Port 11211 is our local Moxi proxy that handles bridging the gap between standard memcached clients and the vbucket-aware traffic that Membase requires. Port 11210 is the direct access port for Membase (both in and out).

Ahh yes, I thought I saw that mentioned somewhere ;) Thanks a bunch for clearing that up. I was having trouble implementing a TAP client and wanted to use the tap.py script to eliminate the possibility it was a server problem. Seems to be giving me some output now.

would you be interested in providing feedback (and then beta testing) a new capability that wraps tap into an extension framework. In this model, your sphinx indexer would be bundled up into a module that could be deployed in membase...and managed as a part of the membase infrastructure...and providing a number of other features that may be interesting to you. This is an active development area over the next couple months for us and would love your feedback/participation if you have the time and interest.
