Stellar has launched RPC integration with a ledger data lake, enabling developers to access any historical ledger from genesis to present through RPC queries. The feature uses SEP-0054 standardized format and can be accessed via public data lakes or self-hosted using Galexie, with the getLedgers endpoint now supporting full historical data retrieval.
Stellar has introduced a new feature that integrates RPC with a ledger data lake, solving the previous limitation where RPC could only access the most recent 7 days of data. The ledger data lake is a cloud-based object store containing metadata for every Stellar ledger from genesis to present, following the SEP-0054 standard. Developers can access this data through publicly hosted data lakes (such as AWS Open Data) or host their own using Galexie, a purpose-built tool for managing and continuously updating ledger data. The getLedgers RPC endpoint now supports querying any historical ledger sequence number. The complete data lake is approximately 3.8TB and grows by roughly 0.5TB annually, with estimated costs of $600 for bootstrap and ~$160/month for ongoing maintenance when self-hosted.
