the taosd memory increased from 8% to 25% after I executed several queries in taos client, why the memory did't go down after the I get query results? Is there any way to free up memory in TDengine database?

根据官方文档https://www.taosdata.com/en/documentation/getting-started可以使用“重置查询缓存”来释放内存。

To clean the schema of local cached tables, execute command RESET QUERY CACHE
