Prerequisites

1. Google Cloud Platform (GCP) Account​

Galexie exports Stellar ledger metadata to Google Cloud Storage (GCS), so you need a GCP account with:

  • Permissions to create a new GCS bucket, or
  • Access to an existing bucket with read/write permissions.

NOTE: While it is possible to natively install Galexie (without Docker), this requires manual dependency management and is recommended only for advanced users.]

Galexie is available as a Docker image, which simplifies installation and setup. Ensure you have Docker Engine installed on your system (Docker installation guide).

Hardware Requirements​

The minimum hardware requirements for running Galexie are:
RAM: 8 GB
CPU: 2 vCPUs
Disk: 100 GB with at least 5K IOPS

Full History Export​

Exporting the full history (as of November 2024):

  • Takes an estimated 150 days using a single instance of Galexie
  • Creates a data lake of approximately 3 TB
  • To speed up the export, multiple instances of Galexie can be executed in parallel, each working on a different range
  • For example, creating the full history for Hubble data lake using about 40 parallel instances (each exporting approximately 1.25 million ledgers) on e2-standard-2 (Google Cloud Platform) takes about 5 days
