Couchdb复制进度监控

Question

请参阅http://wiki.apache.org/couchdb/Replication中的以下代码。请注意，docs_written = docs_read，但progress = 3.为什么不是progress = 100？

另外，couchdb和couchbase之间会有什么区别吗？

$ curl http://localhost:5984/_active_tasks
[
    {
        "pid": "<0.1303.0>",
        "replication_id": "e42a443f5d08375c8c7a1c3af60518fb+create_target",
        "checkpointed_source_seq": 17333,
        "continuous": false,
        "doc_write_failures": 0,
        "docs_read": 17833,
        "docs_written": 17833,
        "missing_revisions_found": 17833,
        "progress": 3,
        "revisions_checked": 17833,
        "source": "http://fdmanana.iriscouch.com/test_db/",
        "source_seq": 551202,
        "started_on": 1316229471,
        "target": "test_db",
        "type": "replication",
        "updated_on": 1316230082
    }
]

Answer 1

因为17333 * 100/551202 = 3。
