upsert_ustb_metadata

Documentation for eth_defi.tokenised_fund.superstate.backfill.upsert_ustb_metadata function.

upsert_ustb_metadata(vault_db, row, end_block)

Upsert only USTB metadata without changing shared discovery cursors.

VaultDatabase.update_leads_and_rows() is the shared merge path, but it also advances the chain-wide discovery cursor. A targeted migration must not make unrelated Ethereum discovery skip blocks, so retain the exact pre-existing cursor value, including the case where no cursor was present, around this single-address upsert.

Parameters

  • vault_db (eth_defi.vault.vaultdb.VaultDatabase) – Existing shared vault database.

  • row (dict) – Fresh USTB scanner metadata row.

  • end_block (int) – Metadata read block supplied to the underlying merge operation.

Returns

None.

Return type

None
