…te_batch When pushing features with array/list types (e.g. STRING_LIST) to BigQuery via offline_write_batch, the data arrives as empty arrays because BigQuery's parquet loader does not infer list structure by default. Set parquet_options.enable_list_inference = True on the LoadJobConfig so array columns are written correctly. Fixes feast-dev#5845 Signed-off-by: Jonathan Wrede <[email protected]>
