Bigtable Reverse Timestamp Generator FAQ
A reverse timestamp is Long.MAX_VALUE minus your timestamp. In Bigtable, this stores rows in descending time order (newest first) since rows are sorted lexicographically.
Bigtable sorts rows in ascending order. Using reverse timestamps puts your most recent data first, improving read performance for time-series queries.
Enter timestamps in milliseconds, seconds (auto-detected), ISO date strings, or just type "now" for current time.
Prepend the reverse timestamp to your row key: reverseTimestamp#entityId. This ensures newest records appear first.
