作者：

Highlights：

• Queries belonging to different topics may have different temporal patterns.

• We propose Static-Topic-Dynamic cache to capture the query stream temporal localities.

• The Static-Topic-Dynamic cache outperforms the traditional Static-Dynamic Cache.

• Hit rate improves up to 3% without admission policy and 4.
