Overview

This is the first major release of snowcap, a fork of Titan Core by Datacoves. The original project appeared unmaintained, so we've forked it to continue active development, fix bugs, and add new features.

Snowcap is a Snowflake infrastructure-as-code tool that lets you manage all Snowflake resources using YAML or Python configuration.

Highlights

  • Renamed from Titan Core to snowcap - Fresh identity, same powerful functionality
  • 1656 tests with 72% code coverage (up from ~400 tests)
  • 60 resource types fully documented
  • Comprehensive documentation at datacoves.github.io/snowcap

New Features

Multithreading Support

  • Added parallel execution for improved performance when managing large numbers of resources
  • Role switching and commands execute concurrently where possible
  • Significant speed improvements for accounts with hundreds of resources

Enhanced Grants System

  • Support for multiple privileges in a single grant definition
  • Grant synchronization mode with sync_resources parameter
  • Fixed bug with ALL privilege type grants
  • Improved handling of grants on non-database/schema resources

Streamlit Resources

  • Full support for Streamlit app resources in Snowflake
  • Create, update, and manage Streamlit applications via configuration

Imported Databases

  • Support for managing imported databases (databases shared from other accounts)
  • Proper handling of cross-account resource references

Jinja Templating Improvements

  • Added parent attribute support in Jinja templates
  • for_each now properly converts strings back to integers when necessary
  • Enhanced template variable handling

Bug Fixes

  • Fixed handling of collection types in resource specifications
  • Fixed quoted names handling for identifiers with special characters
  • Fixed resource type recognition in various edge cases
  • Fixed levels computation when running commands in parallel
  • Fixed refs check when resources are in the manifest but not in the database
  • Fixed parallelism issues in sync mode
  • Fixed role grant fetching from database
  • Database creation now correctly uses ACCOUNTADMIN role
  • Fixed system role modification warnings

Improvements

  • Better error handling throughout the codebase
  • Caching and parallel execution of resource listing operations
  • Improved resource comparison logic
  • Loosened snowflake-connector-python version requirements for better compatibility
  • Enhanced documentation for all resource types

Resource Coverage

snowcap supports 60+ Snowflake resource types including:

  • Compute: Warehouses, Compute Pools
  • Storage: Databases, Schemas, Tables, Views, Dynamic Tables, Materialized Views
  • Security: Roles, Users, Grants, Network Policies, Secrets
  • Data Loading: Stages, Pipes, Streams, Tasks
  • Integrations: Storage Integrations, Notification Integrations, External Access Integrations
  • Governance: Tags, Masking Policies, Row Access Policies, Aggregation Policies
  • Applications: Streamlit, Functions, Procedures, UDFs

Testing Infrastructure

  • Comprehensive unit test suite with 1656 tests
  • Integration tests for Snowflake Standard and Enterprise editions
  • Static test resources for reproducible integration testing
  • 72% code coverage with XML reporting
  • Parallel test execution with pytest-xdist

Migration from Titan Core

If you're migrating from Titan Core:

  1. Update your package: pip install snowcap (instead of titan-core)
  2. Update imports: from snowcap import ... (instead of from titan import ...)
  3. Update CLI commands: snowcap plan/apply (instead of titan plan/apply)
  4. Your existing YAML configurations should work without changes

Requirements

  • Python 3.10 or higher
  • snowflake-connector-python >= 3.12.3
  • snowflake-snowpark-python >= 1.24.0
