Is the query speed affected by the storage data volume

Last Updated: Apr 11, 2018

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.

For more information about query APIs, see GetRow, GetRange, and BatchGetRow.
