For single-row query and range query, the query speed is independent of the data volume.
As a NoSQL database, Table Store allows data volumes to extend linearly alongside cluster scaling without affecting the speeds of single-row query and range query. The query speed does not change even if the data volume reaches the hundred-million-level or ten-billion-level.
On high-performance instances that use SSDs, the querying speed of a single row is at the millisecond-level. If the data volume of a single row is small, the query speed is generally within 10 ms.
