ReverseTM/sdvg: Synthetic Data Values Generator

SDVG (Synthetic Data Values Generator) is a tool for generating synthetic data. It supports various run modes, data types for generation, and output formats.

Run modes:

• CLI - generate data, create configs, and validate them via the console;
• HTTP server - accepts generation requests through an HTTP API.

Data types:

• strings (english, russian);
• integers and floating-point numbers;
• dates with timestamps;
• UUID.

String subtypes:

• random strings;
• texts;
• first names;
• last names;
• phone numbers;
• patterns.

Each data type can be generated with the following options:

• specify percentage/number of unique values per column;
• ordered generation (sequence);
• foreign key reference;
• idempotent generation using a seed number;
• value generation from ranges with percentage-based distribution.

Output formats:

• devnull;
• CSV files;
• Parquet files;
• HTTP API;
• Tarantool Column Store HTTP API.

You can install SDVG by downloading the appropriate binary version from the GitHub Releases page.

Download binary for your OS:

# Linux (x86-64)
curl -Lo sdvg https://github.com/tarantool/sdvg/releases/latest/download/sdvg-linux-amd64

# Linux (ARM64)
curl -Lo sdvg https://github.com/tarantool/sdvg/releases/latest/download/sdvg-linux-arm64

# macOS (x86-64)
curl -Lo sdvg https://github.com/tarantool/sdvg/releases/latest/download/sdvg-darwin-amd64

# macOS (ARM64)
curl -Lo sdvg https://github.com/tarantool/sdvg/releases/latest/download/sdvg-darwin-arm64

Check that everything works correctly:

To compile and install this tool, you can use go install command:

# To get the specified version
go install github.com/tarantool/sdvg@0.0.2
# To get a version from the master branch
go clean -modcache
go install github.com/tarantool/sdvg@latest

Check that everything works correctly:

Here's an example of a data model that generates 10,000 user rows and writes them to a CSV file:

output:
  type: csv
models:
  user:
    rows_count: 10000
    columns:
      - name: id
        type: uuid
      - name: name
        type: string
        type_params:
          logical_type: first_name

Save this as simple_model.yml, then run:

sdvg generate simple_model.yml

This will create a CSV file with fake user data like id and name:

id,name
c8a53cfd-1089-4154-9627-560fbbea2fef,Sutherlan
b5c024f8-3f6f-43d3-b021-0bb2305cc680,Hilton

...
