Documentation for eth_defi.research.sparkline_export.render_sparklines function.

render_sparklines(vault_data, max_workers, backend='processes')

Render one bounded batch using the selected Joblib backend.

Rendering stays batch-bounded so only the current batch’s image payloads need to be returned to the coordinator.

Parameters

• max_workers (int) – Maximum number of concurrent renderer workers.

• backend (str) – Joblib preference, either processes or threads.

Returns

Flattened SVG and PNG payloads for successfully rendered vaults.

Return type
