 **Notes:**
 
-- `start_timestamp` / `end_timestamp` must be >= 0. If both are set, `start_timestamp` must be < `end_timestamp` (time range is [start, end), so `start_timestamp == end_timestamp` produces an empty scan).

 - When `start_rowkey` / `end_rowkey` and `start_timestamp` / `end_timestamp` are configured together, both the rowkey range and the time range constraints are applied (intersection).

 **说明:**
 
-- `start_timestamp` / `end_timestamp` 必须大于等于 0；若两者同时配置，需要满足 `start_timestamp < end_timestamp`（遵循 [start, end) 约定，`start_timestamp == end_timestamp` 将导致空扫描）。

 - 当 `start_rowkey` / `end_rowkey` 与 `start_timestamp` / `end_timestamp` 同时配置时，会同时应用行键范围与时间范围限制，最终返回两者的交集。
