Yes, the replication replicates - there are PUTs and POSTs in the log that could only come from the replication - no other process updates the replica.
doc_count is kept in sync on both source and target. The docs are big (attachments), so 1K docs would be quite a bit of data. source_seq is growing, checkpointed_source_seq still at the same number. Could the difference in the disk_format_version be the reason? Is there some documentation about how replications and checkpoints relate to each other? Thanks for the info on the null value for data_size. -- Andreas ________________________________ From: Paul Davis <[email protected]> To: [email protected]; Andreas Kemkes <[email protected]> Sent: Wednesday, August 22, 2012 3:14 PM Subject: Re: Replications and checkpoints (again) Did the replication actually replicate anything or were they up to date when started? I'm not sure on the exact algorithm continuous replication uses but I wouldn't be surprised if its just every N docs. The example you have is less than 1K docs which wouldn't surprise me as the threshold. data_size being null probably means you haven't compacted that db since upgrade CouchDB.
