Couchbase connection manager

Project description

cb-util 2.2.40

Couchbase Utilities

Couchbase connection manager. Simplifies connecting to a Couchbase cluster and performing data and management operations.

Installing

$ pip install cbcmgr

API Usage

Original syntax (package is backwards compatible):

>>> from cbcmgr.cb_connect import CBConnect
>>> from cbcmgr.cb_management import CBManager
>>> bucket = scope = collection = "test"
>>> dbm = CBManager("127.0.0.1", "Administrator", "password", ssl=False).connect()
>>> dbm.create_bucket(bucket)
>>> dbm.create_scope(scope)
>>> dbm.create_collection(collection)
>>> dbc = CBConnect("127.0.0.1", "Administrator", "password", ssl=False).connect(bucket, scope, collection)
>>> result = dbc.cb_upsert("test::1", {"data": 1})
>>> result = dbc.cb_get("test::1")
>>> print(result)
{'data': 1}

New Operator syntax:

keyspace = "test.test.test"
db = CBOperation(hostname, "Administrator", "password", ssl=False, quota=128, create=True).connect(keyspace)
db.put_doc(col_a.collection, "test::1", document)
d = db.get_doc(col_a.collection, "test::1")
assert d == document
db.index_by_query("select data from test.test.test")
r = db.run_query(col_a.cluster, "select data from test.test.test")
assert r[0]['data'] == 'data'

Thread Pool Syntax:

pool = CBPool(hostname, "Administrator", "password", ssl=False, quota=128, create=True)
pool.connect(keyspace)
pool.dispatch(keyspace, Operation.WRITE, f"test::1", document)
pool.join()

Async Pool Syntax

pool = CBPoolAsync(hostname, "Administrator", "password", ssl=False, quota=128, create=True)
await pool.connect(keyspace)
await pool.join()

CLI Utilities

cbcutil

Load 1,000 records of data using the default schema:

$ cbcutil load --host couchbase.example.com --count 1000 --schema default

Load data from a test file:

$ cat data/data_file.txt | cbcutil load --host couchbase.example.com -b bucket

Export data from a bucket to CSV (default output file location is $HOME)

$ cbcutil export csv --host couchbase.example.com -i -b sample_app

Export data as JSON and load that data into another cluster

$ cbcutil export json --host source -i -O -q -b bucket | cbcutil load --host destination -b bucket

Get a document from a bucket using the key:

$ cbcutil get --host couchbase.example.com -b employees -k employees:1

List information about a Couchbase cluster:

$ cbcutil list --host couchbase.example.com -u developer -p password

List detailed information about a Couchbase cluster including health information:

$ cbcutil list --host couchbase.example.com --ping -u developer -p password

Replicate buckets, indexes and users from self-managed cluster to Capella (and filter buckets beginning with "test" and users with usernames beginning with "dev"):

cbcutil replicate source --host 1.2.3.4 --filter 'bucket:test.*' --filter 'user:dev.*' | cbcutil replicate target --host cb.abcdefg.cloud.couchbase.com -p "Password123#" --project dev-project --db testdb

List available schemas:

$ cbcutil schema

Randomizer tokens

Note: Except for the US States the random data generated may not be valid. For example the first four digits of the random credit card may not represent a valid financial institution. The intent is to simulate real data. Any similarities to real data is purely coincidental.

rand_credit_card Random credit card format number
rand_ssn Random US Social Security format number
