couchdb - CouchDB Fauxton _replicator db: exclamation stating "This database has just X docs and Y deleted docs"

Question

I am using Fauxton on Apache CouchDB, version 2.3.1.

Next to the # of Docs field for my _replicator db, there is an exclamation point. When I hover over it, it says: This database has just 4 docs and 5 deleted docs.

Here is a screenshot of what I'm seeing.

The replicator DB does have 4 docs inside (_design/_replicator doc + 3 replication configs).

I can't find this warning mentioned in the CouchDB docs anywhere. What does it mean, and is it a bad thing?

Answer 1

它是数据库信息的一部分（请参阅 doc_del_count）。基本上，当您删除文档时，数据库中会保留一个墓碑，以便复制协议可以正确同步文档。

你不应该担心这个。一旦压缩，墓碑只保留非常少的不影响性能的信息。

如果由于某些原因您需要删除_deleted文档，您可以清除它们或对_deleted文档进行过滤复制。
