SochDB v0.3.1 Release Notes

Release Date: January 4, 2026
Type: Minor Release
Status: Stable

🎯 Overview​

SochDB v0.3.1 introduces optional, privacy-respecting usage analytics to help improve the database while maintaining user privacy. This release adds anonymous usage information collection with full transparency and user control.

✨ What's New​

Anonymous Usage Analytics​

Optional telemetry to understand how SochDB is used in production, with strict privacy guarantees:

Events Tracked​

  1. database_opened — Sent once when database is initialized

    • Properties: mode (embedded/server), has_custom_path (boolean)
    • Helps understand deployment patterns

  2. error — Static error tracking for reliability improvements

    • Properties: error_type (category), location (code path)
    • No dynamic error messages — only static identifiers
    • Example: "query_error" at "sql.execute" (no SQL queries, no user data)

Privacy Guarantees​

✅ Anonymous ID — Stable SHA-256 hash of machine info (hostname, OS, arch)
✅ No PII — No usernames, file paths, query content, or error messages
✅ Opt-out — Set SOCHDB_DISABLE_ANALYTICS=true to disable completely
✅ Optional Dependencies — Graceful degradation if analytics libraries unavailable
✅ Open Source — All analytics code visible in repository

SDK Implementation​

Python SDK:

from sochdb import Database
from sochdb.analytics import capture_error

# Analytics automatically tracks database_opened
db = Database.open("./mydb")

# Track errors (static info only)
try:
    db.execute(query)
except Exception:
    capture_error("query_error", "sql.execute")

Installation with analytics:

pip install sochdb[analytics]  # Includes posthog
# or
pip install sochdb  # Works without analytics

JavaScript SDK:

import { Database, captureError } from '@sochdb/sochdb';

// Analytics automatically tracks database_opened
const db = await Database.open('./mydb');

// Track errors (static info only)
try {
  await db.execute(query);
} catch (err) {
  await captureError('query_error', 'sql.execute');
}

Installation:

npm install @sochdb/sochdb
# posthog-node is optionalDependency (works without it)

Rust SDK:

use sochdb_core::analytics;

// Enable analytics feature in Cargo.toml
// sochdb-core = { version = "0.4.0", features = ["analytics"] }

let db = Database::open("./mydb")?;
analytics::analytics().track_database_open("./mydb", "embedded");

// Track errors
if let Err(_) = db.query(sql) {
    analytics::capture_error("query_error", "query::execute");
}

Disabling Analytics​

Set environment variable before running your application:

export SOCHDB_DISABLE_ANALYTICS=true
python your_app.py

# Or inline
SOCHDB_DISABLE_ANALYTICS=true ./your_binary

No events will be sent when disabled.

🔧 Improvements​

Documentation Updates​

  • Updated all version references from 0.2.9 to 0.3.1
  • Updated installation guides for Python, JavaScript, Rust, Go
  • Consistent versioning across all SDK documentation
  • Updated benchmark metadata in README

Build System​

  • Rust: Analytics feature enabled by default in client crates
    • sochdb, sochdb-python, sochdb-grpc include analytics
    • Added json feature to ureq for PostHog API calls
  • JavaScript: Fixed ESM import paths for analytics module
  • Python: Analytics as optional dependency group

🐛 Bug Fixes​

  • JavaScript: Fixed ESM import requiring .js extension in database.ts
  • Rust: Fixed analytics payload structure for PostHog API
  • Tests: Updated version expectations in JavaScript tests (0.3.0 → 0.3.1)

📦 Installation​

Python​

pip install sochdb==0.3.1

# With analytics support
pip install sochdb[analytics]==0.3.1

JavaScript / Node.js​

npm install @sochdb/sochdb@0.3.1

Rust​

[dependencies]
sochdb = "0.4.0"

# Or with analytics
sochdb-core = { version = "0.4.0", features = ["analytics"] }

Go​

go get github.com/sochdb/sochdb-go@v0.3.1

🧪 Testing​

All SDKs fully tested:

  • ✅ Python: Analytics integration verified
  • ✅ JavaScript: 74 tests passing
  • ✅ Rust: 362 tests passing (1 flaky test in parallel HNSW)

Test analytics locally:

# Python
python test_error_tracking.py

# JavaScript
node test_error_tracking.js

# Rust
cd test_analytics_rust && cargo run

🔐 Privacy & Security​

What Data is Collected?​

When database_opened event fires:

{
  "event": "database_opened",
  "distinct_id": "0c628825688f52aa",
  "properties": {
    "mode": "embedded",
    "has_custom_path": true,
    "sdk": "python",
    "sdk_version": "0.4.0",
    "os": "Darwin",
    "arch": "x86_64"
  }
}

When error event fires:

{
  "event": "error",
  "distinct_id": "0c628825688f52aa",
  "properties": {
    "error_type": "connection_error",
    "location": "database.open",
    "sdk": "python",
    "sdk_version": "0.4.0",
    "os": "Darwin",
    "arch": "x86_64"
  }
}

What is NOT collected:

  • ❌ File paths
  • ❌ Database names
  • ❌ Query content
  • ❌ Error messages
  • ❌ User data
  • ❌ IP addresses
  • ❌ Hostnames (hashed only)

Anonymous ID Generation​

# Stable hash of machine-specific info
machine_info = [hostname, os, arch, uid]
anonymous_id = sha256("|".join(machine_info))[:16]
# Example: "0c628825688f52aa"

Same machine always gets same ID, but ID cannot be reversed to identify the machine.

🔄 Migration Guide​

From v0.3.0 to v0.3.1​

No breaking changes. This is a backward-compatible minor release.

Optional: Install analytics dependencies if you want to contribute usage data:

# Python
pip install posthog>=3.0.0

# JavaScript (already in optionalDependencies)
npm install posthog-node

# Rust (already enabled via features)
# No action needed

Opt-out: Add to your deployment configuration:

# .env file
SOCHDB_DISABLE_ANALYTICS=true

# Docker
ENV SOCHDB_DISABLE_ANALYTICS=true

# Kubernetes
env:
  - name: SOCHDB_DISABLE_ANALYTICS
    value: "true"
