zerodb-temporal 0.1.0

ZeroDB event connector for Temporal workflows. Bridge ZeroDB events to Temporal.

zerodb-temporal

ZeroDB event connector for Temporal workflows.

Bridge ZeroDB database events to Temporal's durable execution engine.

Why use this?

Feature	Description
Event-driven	ZeroDB events automatically trigger Temporal workflows
Durable	Temporal guarantees workflow completion even through failures
Activity helpers	Store results, memories, files, and vectors back to ZeroDB
Auto-provision	No signup needed -- ZeroDB project created on first use
Webhook + polling	Two modes: poll event stream or receive webhooks
Connector pattern	Bridges ZeroDB and Temporal -- doesn't replace either

Installation

pip install zerodb-temporal

Quick Start

Basic Trigger

from zerodb_temporal import ZeroDBTrigger, ZeroDBActivity

# Listen for file upload events
trigger = ZeroDBTrigger(event_type='zerodb.file.uploaded')

@trigger.on_event
async def process_file(event):
    print(f"File uploaded: {event.data}")

    # Store result back to ZeroDB
    activity = ZeroDBActivity()
    activity.store_result({
        'file_id': event.data.get('file_id'),
        'status': 'processed',
    })
    return {'processed': True}

# Start polling for events
trigger.start()

Connector Pattern (Multiple Event Types)

from zerodb_temporal import ZeroDBTemporalConnector

connector = ZeroDBTemporalConnector(
    temporal_host='localhost:7233',
    task_queue='zerodb-events',
)

@connector.workflow('zerodb.file.uploaded')
async def handle_upload(event):
    result = connector.activity.store_result({
        'event': event.event_id,
        'status': 'processed',
    })
    return result

@connector.workflow('zerodb.table.insert')
async def handle_new_row(event):
    connector.activity.store_memory(
        f"New row inserted in {event.data.get('table')}",
        tags=['db-event'],
    )
    return {'acknowledged': True}

# Start all triggers
import asyncio
asyncio.run(connector.run())

Webhook Mode

from flask import Flask, request
from zerodb_temporal import ZeroDBTemporalConnector

app = Flask(__name__)
connector = ZeroDBTemporalConnector()

@connector.workflow('zerodb.file.uploaded')
def handle_upload(event):
    return {'processed': True}

@app.post('/webhook/zerodb')
def webhook():
    results = connector.process_webhook(request.json)
    return {'results': results}

connector.start()	Start all triggers
connector.stop()	Stop all triggers
await connector.run()	Run blocking (async)
connector.process_webhook(payload)	Route webhook to correct workflow

ZeroDBEvent

Event data wrapper.

Field	Type	Description
event_type	str	Event type string
event_id	str	Unique event ID
data	dict	Event payload
timestamp	str	ISO 8601 timestamp
project_id	str	ZeroDB project ID
metadata	dict	Additional metadata

EventType Constants

Constant	Value
TABLE_INSERT	zerodb.table.insert
TABLE_UPDATE	zerodb.table.update
TABLE_DELETE	zerodb.table.delete
FILE_UPLOADED	zerodb.file.uploaded
FILE_DELETED	zerodb.file.deleted

Configuration

Environment Variables

export ZERODB_API_KEY="your-api-key"
export ZERODB_PROJECT_ID="your-project-id"
# Optional
export ZERODB_BASE_URL="https://api.ainative.studio"

Auto-Provisioning

If no credentials are found, zerodb-temporal automatically creates a free ZeroDB project on first use. Credentials are saved to ~/.zerodb/config.json.

Use Cases

ETL Pipeline

@connector.workflow('zerodb.file.uploaded')
async def etl_pipeline(event):
    # Download uploaded file
    raw = connector.activity.download_file(event.data['path'])

    # Transform
    processed = transform(raw)

    # Store result
    connector.activity.store_result({
        'source': event.data['path'],
        'rows_processed': len(processed),
    })

AI Agent Memory

@connector.workflow('zerodb.table.insert')
async def enrich_memory(event):
    row = event.data.get('row', {})
    connector.activity.store_memory(
        f"User {row.get('name')} registered from {row.get('source')}",
        entity_id=row.get('user_id'),
        tags=['registration', 'user-event'],
    )

Event Chain

@connector.workflow('zerodb.hook.completed')
async def chain_next(event):
    # Trigger next step in pipeline
    connector.activity.create_event(
        'zerodb.custom',
        {'step': 'next', 'previous_result': event.data},
    )
