Oracle NoSQL Database Python SDK

Project description


This is the Python SDK for Oracle NoSQL Database. Python versions 3.5+ are supported. The SDK provides interfaces, documentation, and examples to help develop Python applications that connect to the Oracle NoSQL Database Cloud Service, Oracle NoSQL Database and to the Oracle NoSQL Cloud Simulator (which runs on a local machine).

In order to run the Oracle NoSQL Cloud Simulator, a separate download is necessary from the Oracle NoSQL OTN download page. Throughout the documentation, the Oracle NoSQL Database Cloud Service and Cloud Simulator are referred to as the “cloud service” while the Oracle NoSQL Database is referred to as “on-premise.” In the API reference classes and interfaces are noted if they are only relevant to a specific environment.

The on-premise configuration requires a running instance of the Oracle NoSQL database. In addition a running proxy service is required. See Oracle NoSQL Database Downloads for downloads, and see Information about the proxy for proxy configuration information.

This project is open source and maintained by Oracle Corp. The home page for the project is here.


The SDK can be installed using pip. If using Python 3 the command may be pip3:

pip install borneo

If you are using the Oracle NoSQL Database cloud service you will also need to install the oci package:

pip install oci

See the installation guide for additional requirements and and alternative install methods.


Examples can be found on GitHub.

Examples include simple, standalone programs. They include comments about how they can be configured and run in the different supported environments.


The documentation has information on using the SDK as well as an API reference describing the classes.


See the Changelog.


When requesting help please be sure to include as much detail as possible, including version of the SDK and simple, standalone example code as needed.


The following is a quick start tutorial to run a simple program in the supported environments. The same template source code is used for all environments. The first step is to cut the program below and paste it into an editor for minor modifications. The instructions assume that is stored as, but you can use any name you like. The quickstart example supports 3 environments:

  1. Oracle NoSQL Database Cloud Service

  2. Oracle NoSQL Cloud Simulator

  3. Oracle NoSQL Database on-premise, using the proxy server

See Running Quickstart to run the quickstart program in different environments. The instructions assume that the borneo package has been installed.

# This is a simple quickstart to demonstrate use of the Python driver for
# the Oracle NoSQL Database. It can be used to run against the Oracle NoSQL
# Database Cloud Service, against the Cloud Simulator, or against an
# on-premise Oracle NoSQL database.
# Usage:
#   python <cloud | cloudsim | kvstore>
# Use cloud for the Cloud Service
# Use cloudsim for the Cloud Simulator
# Use kvstore for the on-premise database
# This example is not intended to be an exhaustive overview of the API,
# which has a number of additional operations.
# Requirements:
#  1. Python 3.5+
#  2. Python dependencies (install using pip or other mechanism):
#   o requests
#   o oci (only if running against the Cloud Service)
#  3. If running against the Cloud Simulator, it can be downloaded from
#  here:
#  It requires Java
#  4. If running against the Oracle NoSQL Database Cloud Service an account
#  must be used.

Running Quickstart

Run Against the Oracle NoSQL Database Cloud Service

Running against the Cloud Service requires an Oracle Cloud account. See Configure for the Cloud Service for information on getting an account and acquiring required credentials.

  1. Collect the following information:

  • Tenancy ID

  • User ID

  • API signing key (private key file in PEM format)

  • Fingerprint for the public key uploaded to the user’s account

  • Private key pass phrase, needed only if the private key is encrypted

  1. Edit and add your information. There are 2 ways to supply credentials in the program:

    • Directly provide the credential information. To use this method, modify the values of the variables at the top of the program: tenancy, user, private_key, fingerprint, and pass_phrase, setting them to the corresponding information you’ve collected.

    • Using a configuration file. In this case the information you’ve collected goes into a file, ~/.oci/config. Configure for the Cloud Service describes the contents of the file. It will look like this:

  2. Decide which region you want to use and modify the cloud_region variable to the desired region. See Regions documentation for possible regions. Not all support the Oracle NoSQL Database Cloud Service.

  3. Run the program:

python cloud

Run Against the Oracle NoSQL Cloud Simulator

Running against the Oracle NoSQL Cloud Simulator requires a running Cloud Simulator instance. See Configure for the Cloud Simulator for information on how to download and start the Cloud Simulator.

  1. Start the Cloud Simulator based on instructions above. Note the HTTP port used. By default it is 8080 on localhost.

  2. The program defaults to localhost:8080 so if the Cloud Simulator was started using default values no editing is required.

  3. Run the program:

python cloudsim

Run Against Oracle NoSQL on-premise

Running against the Oracle NoSQL Database on-premise requires a running Oracle NoSQL Database instance as well as a running NoSQL Proxy server instance. The program will connect to the proxy server.

See Configure for On-Premise Oracle NoSQL Database for information on how to download and start the database instance and proxy server. The database and proxy should be started without security enabled for this quickstart program to operate correctly. A secure configuration requires a secure proxy and more complex configuration.

  1. Start the Oracle NoSQL Database and proxy server based on instructions above. Note the HTTP port used. By default the endpoint is localhost:80.

  2. The program defaults to localhost:80. If the proxy was started using a different host or port edit the settings accordingly.

  3. Run the program:

python kvstore
