CouchDB Filtered Replication – Group of Doc’s Don’t appear to be batched (see thread)

A user has issues with a filter doing a simple check and making syncing from a couch instance to another much slower. The questions: “Does CouchDB filter replication not group docs and send 1 doc in each _bulk_docs call to the target host? Is there some configuration which would allow the filter replication to group docs to speed up replication?”

It is discussed if the replicator is faster than the filter function in this case, and if to request ‘filtered _changes feed’ to check the throughput speed.

A possible explanation states that the “replicator will dynamically choose ‘_bulk_docs’ batch sizes based on the number of documents that are ready to be transmitted to the source” and that it is currently “possible to set an upper bound on the size”, but not a lower. Though other referred issues imply that batch size doesn’t seem to be configurable.

Time to relax!

  • “I’ve had an engineer on salary at a bootcamp message me to explicitly “be friends with benefits” while I was in the interview process at the school he worked for. I would like to add that both men responsible for these unfavorable experiences are not bad people. They are both socially-accepted, “smart” and “normal” guys. This illustrates one of the industry’s deep underlying issues.” – You May Have Seen My Face on BART
  • “‘Segment the product by quality, value and personal image—ideas that all ended up leading to the thriving coffee market of today. Just when we thought we were out, they sucked us back in. (Meanwhile, the parallel rise of coffee and decline of tobacco could be a sociology thesis, in and of itself.)’ That little insight is part of a three-part series on the anthropology of coffee on the blog Anthropology in Practice.” – The anthropology of coffee
  • “The future belongs to all of us—or, ultimately, none of us—why does it matter if the vast majority of futurists are white men? It matters for the same reasons diversity drives market growth: because when only one type of person is engaged in asking key questions about a specialty—envisioning the future or otherwise—they miss entire frameworks for identifying and solving problems.” – Why Aren’t There More Women Futurists?
  • “‘It is important to recreate that ‘water cooler’ conversation that naturally occurs in a traditional office,’ […] Staying focused on work is important, but taking a moment to ask your colleagues about their weekends, hobbies, families and other personal activities strengthens those bonds and leads to a higher-functioning team.” – 5 ways to make working remotely actually work
