Configuration

(vdk config-help is useful command to browse all config options of your installation of vdk)

Example

CLI Queries

export VDK_ORACLE_USER=my_username

Note: Running CLI queries does not support secrets

Ingestion

import datetime
from decimal import Decimal

def run(job_input):

    # Ingest object
    payload_with_types = {
        "id": 5,
        "str_data": "string",
        "int_data": 12,
        "float_data": 1.2,

        "timestamp_data": datetime.datetime.fromtimestamp(1700554373),
        "decimal_data": Decimal(0.1),
    }

    job_input.send_object_for_ingestion(
        payload=payload_with_types, destination_table="test_table"
    )

    # Ingest tabular data
    col_names = [
        "id",
        "str_data",
        "int_data",

    job_input.send_tabular_data_for_ingestion(
        rows=row_data, column_names=col_names, destination_table="test_table"
    )

Ingestion with type inference

Ingestion works with an already created table even if you pass strings in the payload. vdk-oracle infers the correct type based on the existing table.

create table test_table (
    id number,
    str_data varchar2(255),
    int_data number,
    float_data float,
    bool_data number(1),
    timestamp_data timestamp,
    decimal_data decimal(14,8),
    primary key(id))

def run(job_input):
    payload = {
        "id": "5",
        "str_data": "string",
        "int_data": "12",
        "float_data": "1.2",
        "bool_data": "False",
        "timestamp_data": "2023-11-21T08:12:53",
        "decimal_data": "0.1",
    }

    job_input.send_object_for_ingestion(payload=payload, destination_table="test_table")

Build and testing

pip install -r requirements.txt
pip install -e .
pytest

In VDK repo ../build-plugin.sh script can be used also.

Note about the CICD:

.plugin-ci.yaml is needed only for plugins part of Versatile Data Kit Plugin repo.

The CI/CD is separated in two stages, a build stage and a release stage. The build stage is made up of a few jobs, all which inherit from the same job configuration and only differ in the Python version they use (3.7, 3.8, 3.9 and 3.10). They run according to rules, which are ordered in a way such that changes to a plugin's directory trigger the plugin CI, but changes to a different plugin does not.
