eTiKeT Sync Agent - Core Tools Connector

Connector for synchronizing core_tools datasets with the eTiKeT platform. This connector reads measurements from core_tools PostgreSQL databases and syncs them to the cloud.

Installation

This connector depends on core_tools and pulse_lib, which are hosted on a private TU Delft GitLab repository. You must have these packages cloned locally and install them from their folder locations.

from etiket_sdk.sync import Connectors

# 1. Install dependencies from local folders
Connectors.install_from_local("/path/to/pulse_lib")
Connectors.install_from_local("/path/to/core_tools")

# 2. Install the connector
Connectors.install_from_pypi("etiket-sync-agent-core-tools")

The package is automatically discovered by etiket_sync_agent through the entry-point system. Once installed, you can verify with:

print(Connectors.list())
connector = Connectors.get("etiket_sync_agent_core_tools")
print(connector)

What Gets Synchronized

When a core_tools measurement is synced, the following data is extracted and uploaded:

Additional Metadata

The connector also extracts and synchronizes:

1. Snapshot data: Instrument settings stored in the measurement snapshot
2. Pulses data: AWG pulse sequences (if available in snapshot)
3. Gates data: Gate voltages (if available in snapshot)

Configuration

The core_tools connector requires a CoreToolsConfigData configuration with the following fields:

Example Configuration

from etiket_sync_agent_core_tools import CoreToolsConfigData

config = CoreToolsConfigData(
    dbname="my_experiments",
    user="postgres",
    password="secret",
    host="localhost",
    port=5432
)

Scope Mapping

Core_tools supports the concept of scope (or project in older versions) to organize measurements. When syncing, the connector maps core_tools scopes to eTiKeT scopes.

How Scope Mapping Works

1. If scope exists in core_tools: The scope name is used as the scope_identifier
2. If scope is None: A generated identifier is used: CT_PROJECT_{project_name}

Assigning Scope Mappings

After datasets are discovered, the user must map the scope_identifier to an actual eTiKeT scope. There are two ways to do this:

1. Auto-assignment: If the scope_identifier exactly matches an existing eTiKeT scope name, use the auto-assign feature
2. Manual mapping: Use the etiket_sdk or the DataQruiser GUI to manually map identifiers to scopes

For more information, see the etiket_sdk documentation or use our GUI application (DataQruiser).

Features

• Direct integration with core_tools PostgreSQL databases
• Automatic metadata extraction from snapshots
• Live sync support for running measurements
• Pulse sequence extraction from AWG instruments
• Gate voltage extraction in the metadata of the hdf5 file.

Live Measurement Sync

The core_tools connector supports live synchronization of in-progress measurements. When a measurement is detected as "running", the sync agent:

1. Creates the dataset entry in eTiKeT
2. Streams data points as they are written to the database
3. Uploads pulse metadata (if available)
4. Marks the dataset as complete when the measurement finishes

Timeout Handling

If no new data is written for 30 minutes, the live sync assumes the measurement has stalled and raises a timeout error.

Requirements

• Python >= 3.10
• core_tools (private package from TU Delft GitLab)
• PostgreSQL database with core_tools schema
