quantlab.acquisition.sharadar.raw_tier.write_table_watermark(vendor_root, code, through)[source]#

Record that a table’s raw tier is complete through through.

Written after a bulk pull (the day of the pull) and after each date-window or updated pull, once its rows are on disk; an interrupted pull leaves the previous one. Read back by quantlab.dataset.sharadar.tables.read_watermark.
