Sync Gateway : configuring shadow bucket

[Tim Clarke]

Is bucket shadowing still supported in Sync Gateway v1.1.1 and where do I find the documentation?  The "shadow" setting no longer appears in the config.json documentation, and this link no longer works (previous mentioned by Jens Alfke in this post)

We have two couchbase servers sharing a bucket. A CMS publishes to the bucket, then this is shadowed to another bucket that sync gateway uses with pull replication from mobile clients. This is all done by using snippets of config.json found in various forum posts.

Sync Gateway is on both servers and load balanced, but I'm concerned that only one node can run the shadowing otherwise problems occur. It seems like the best practice is to use multiple nodes for resilience, but then we're forced to only have one server running shadowing which is a single-point-of failure.

What's more concerning is I can't find documentation on the shadow feature, so is it being dropped?

Tim,

I asked a similar question months ago and the question went unanswered.

I was informed by a couchbase employee over drinks that the documentation for shadowing had been silently removed.  That's all I was told about the future of the product.

Because of this ambiguity, we actually decided to move away from couchbase lite and sync gateway for our product.  I don't know for certain that shadow buckets are going away, but the future of shadowing seemed tenuous enough that we didn't want to take the risk.

thanks for the honest reply - I'm more concerned now, but much better informed :-)
