Old Faithful Switches Over: Compact Indexes Live, Legacy Formats End at Epoch 1020
Triton One ships compact indexes for Solana's historical data in Old Faithful — smaller and faster. The legacy formats end at epoch 1020, expected around August 21. Anyone running historical queries needs to migrate.
What Happened
Triton One has shipped compact indexes for Old Faithful — the open archive of Solana’s historical data: considerably smaller and faster than the previous formats. The reader tooling Jetstreamer 0.7.0 consumes the new indexes natively. At the same time comes a fixed sunset: the legacy index formats (such as slot-to-cid) end at epoch 1020 — at the current epoch cadence, expected around August 21.
The underlying CAR archive files remain; anyone needing the old indexes can regenerate them from those.
Who This Affects
Old Faithful is the standard source when applications query historical Solana data — older transactions, past epochs, long-range analytics. Affected is every pipeline built on the previous index formats: analytics and forensics tooling, indexers, archive nodes, data agents. The migration is small but on a clock — after epoch 1020, queries against the old indexes go nowhere until switched to the compact formats or regeneration.
Context
The step fits the ongoing consolidation of Solana’s data layer: tokens.xyz was open-sourced, Coinbase opened a SQL interface — and the historical archive tier now gets more efficient and consolidated at once. Triton most recently worked on the access layer with HTTP/3 QUIC for Solana RPCs.
Note: This is reporting, not investment advice.
What to Watch
- Whether the ecosystem migrates broadly before epoch 1020
- How large the speed and storage gains of the compact indexes turn out in practice
