xeze-dbr-core 0.1.0

Official unified database wrapper for the Xeze infrastructure.

xeze-dbr-core

Official unified database wrapper for the Xeze infrastructure. Provides a single, heavily-abstracted client for PostgreSQL, MongoDB, and Redis over mTLS via HashiCorp Vault.

Installation

pip install git+https://code.xeze.org/xeze/xeze-dbr-core.git

Or install locally for development:

pip install .

Quick Start

from xeze_core import XezeCoreClient

db = XezeCoreClient(app_namespace="xms")
db.init_workspace()  # Ensures the 'xms_pg' database exists

# Postgres
db.pg_insert("students", {"name": "Ayush", "grade": "A"})

# MongoDB
db.mongo_insert("audit_logs", {"action": "student_added", "timestamp": "2026-04-05"})

# Redis
db.redis_set("cache:student:latest", "Ayush", ttl=300)

Environment Variables

Variable	Default	Description
VAULT_ADDR	http://127.0.0.1:8200	HashiCorp Vault address
VAULT_TOKEN	dev-root-token	Vault authentication token
DB_ROUTER_HOST	db.0.xeze.org:443	Database Router gRPC host

Architecture

• Database-per-Service isolation — each app_namespace gets its own {ns}_pg, {ns}_mongo, and {ns}: Redis prefix.
• Vault mTLS — client certs are fetched from Vault KV at dbrouter/certs and loaded in-memory only.
• gRPC/Protobuf abstraction — all Protobuf packing is handled internally; developers work with native Python dicts.
