Overview
In the "Replicator DB Activity" tab of the Replication panel
add the message "Up to about 100 replications are displayed."
When there are many _replicator documents, users are puzzled
when some replications do not show up in the
Replicator DB Activity
panel of the Replication panel.In my test using Cloudant I found that the number of replications
displayed in the
Replicator DB Activity
tab of the Replication panel was 99.That must be because we get 100 _replicator documents at:
https://github.com/apache/couchdb-fauxton/blob/main/app/addons/replication/api.js#L314
const url = Helpers.getServerUrl('/_replicator/_all_docs?include_docs=true&limit=100');
And then at https://github.com/apache/couchdb-fauxton/blob/main/app/addons/replication/api.js#L321
we filter out all the design documents:
return parseReplicationDocs(res.rows.filter(row => row.id.indexOf("_design/") === -1));
And in Cloudant the _replicator database is created with a
design document _design/_replicator.
So of the 100 _replicator documents that were retrieved,
one was filtered out, leaving 99 replications to be displayed
in the "Replicator DB Activity" tab of the Replication panel.
When I tried the same thing with Apache CouchDB,
the _replicator document did not contain any design documents,
so 100 replications were displayed.
