V3IO Frames

V3IO Frames ("Frames") is a multi-model open-source data-access library that provides a unified high-performance DataFrame API for working with different types of data sources (backends). The library was developed by Iguazio to simplify working with data in the Iguazio Data Science Platform ("the platform"), but it can be extended to support additional backend types.

Python Version

The current version of Frames supports Python 3.6 and 3.7.

Initialization

To use Frames, you first need to import the v3io_frames Python library. For example:

import v3io_frames as v3f

Then, you need to create and initialize an instance of the Client class; see Client Constructor. You can then use the client methods to perform different data operations on the supported backend types.

Backend Types

All Frames client methods receive a backend parameter for setting the Frames backend type. Frames currently supports the following backend types:

• nosql | kv — a platform NoSQL (key/value) table.
  
  

  Note: The documentation uses the "nosql" alias to the "kv" type, which was added in Frames v0.6.10-v0.9.13; "kv" is still supported for backwards compatibility with earlier releases.

• stream — a platform data stream [Tech Preview].
• tsdb — a time-series database (TSDB).
• csv — a comma-separated-value (CSV) file. This backend type is used only for testing purposes.

Client Methods

The Client class features the following methods for supporting operations on a data collection, such as a NoSQL or TSDB table or a data stream:

• create — creates a new collection.
• delete — deletes a collection or specific items of the collection.
• read — reads data from a collection into pandas DataFrames.
• write — writes data from pandas DataFrames to a collection.
• execute — executes a backend-specific command on a collection. Each backend may support multiple commands.
• history — returns information about requests made to the service.

Note: Some methods or method parameters are backend-specific, as detailed in this reference.

User Authentication

When creating a Frames client, you must provide valid credentials for accessing the backend data, which Frames will use to identify the identity of the user. This can be done by using any of the following alternative methods (documented in order of precedence).

• Provide the authentication credentials in the call to the Client constructor — either by setting the token parameter to a valid authentication token (access key) or by setting the user and password parameters to a username and password. Note that you cannot set the token parameter concurrently with the username and password parameters.

• Provide the authentication credentials in environment variables — either by setting the V3IO_ACCESS_KEY variable to an authentication token or by setting the V3IO_USERNAME and V3IO_PASSWORD variables to a username and password.

  Note:

  • When V3IO_ACCESS_KEY is defined, V3IO_USERNAME and V3IO_PASSWORD are ignored.
  • When the client constructor is called with authentication parameters (option #1), the authentication-credentials environment variables (if defined) are ignored.

Client Constructor

All Frames operations are executed via an object of the Client class.

• Syntax
• Parameters and Data Members
• Return Value
• Examples

Syntax

Client(address=""[, data_url=""], container=""[, user="", password="", token=""])

Parameters and Data Members

• address — The address of the Frames service (framesd). Use the grpc:// prefix for gRPC (default; recommended) or the http:// prefix for HTTP. When running locally on the platform, set this parameter to framesd:8081 to use the gRPC (recommended) or to framesd:8080 to use HTTP.

  • Type: str
  • Requirement: Required

• data_url — A web-API base URL for accessing the backend data. By default, the client uses the data URL that's configured for the Frames service; for the platform backends, this is typically the HTTPS URL of the web-APIs service of the parent tenant.

  • Type: str
  • Requirement: Optional

• container — The name of the data container that contains the backend data. For example, "bigdata" or "users".

  • Type: str
  • Requirement: Required

• user — The username of a user with permissions to access the backend data. See User Authentication.

  • Type: str
  • Requirement: Required when neither the token parameter or the authentication environment variables are set.
    When the user parameter is set, the password parameter must also be set to a matching user password.

• password — A valid password for the user configured in the user parameter. See User Authentication.

  • Type: str
  • Requirement: Required when the user parameter is set.

• token — A valid token that allows access to the backend data, such as a platform access key for the platform backends. See User Authentication.

  • Type: str
  • Requirement: Required when neither the user or password parameters or the authentication environment variables are set.

Return Value

Returns a new Frames Client data object.

Examples

The following examples, for local platform execution, both create a Frames client for accessing data in the "users" container by using the authentication credentials of user "iguazio"; the first example uses token (access-key) authentication while the second example uses username and password authentication (see User Authentication):

import v3io_frames as v3f
client = v3f.Client("framesd:8081", token="e8bd4ca2-537b-4175-bf01-8c74963e90bf", container="users")

import v3io_frames as v3f
client = v3f.Client("framesd:8081", user="iguazio", password="mypass", container="users")

Common Client Method Parameters

All client methods receive the following common parameters; additional, method-specific parameters are described for each method.

• backend — The backend data type for the operation. See Backend Types.

  • Type: str
  • Requirement: Required
  • Valid Values: "nosql" | "stream" | "tsdb" | "csv" (for testing)

  • Type: str
  • Requirement: Required unless otherwise specified in the method-specific documentation

create Method

Creates a new data collection in the configured client data container, according to the specified backend type.

Note: The create method isn't applicable to the nosql backend, because NoSQL tables in the platform don't need to be created prior to ingestion; when ingesting data into a table that doesn't exist, the table is automatically created.
