Is it possible to open and view the _dbs.couch under the data directory

[zssai]

After installation, under the data directory, there are four databases, _dbs.couch, _nodes.couch, _replicator.couch and _users.couch. Is it possible to open and view the _dbs.couch database

[nickva]

@zssai yes, you may view those databases. They are node-local (not clustered), so you could access them via /_node/_local/_dbs for example. Instead of _local you may use a specific node name [email protected] too.

_dbs would contain shards for clustered databases. It's a database of database docs :-)

http put $DB/mydb

http $DB/_node/_local/_dbs/mydb
HTTP/1.1 200 OK

{
    "_id": "mydb",
    "_rev": "1-275115469f6f9a8469008e5e5a929d2c",
    "by_node": {
        "[email protected]": [
            "00000000-7fffffff",
            "80000000-ffffffff"
        ]
    },
    "by_range": {
        "00000000-7fffffff": [
            "[email protected]"
        ],
        "80000000-ffffffff": [
            "[email protected]"
        ]
    },
    "changelog": [
        [
            "add",
            "00000000-7fffffff",
            "[email protected]"
        ],
        [
            "add",
            "80000000-ffffffff",
            "[email protected]"
        ]
    ],
    "props": {},
    "shard_suffix": [
        46,
        49,
        54,
        52,
        53,
        55,
        50,
        49,
        48,
        48,
        56
    ]
}

A word of warning: modifying them by hand unless you're aware of the CouchDB internals may render your cluster unusable and you may lose data.
