   > hi@wenjin272 [@avx-wlauer](https://github.com/avx-wlauer) , If short-term 
memory can be converted into long-term memory through some mechanism, wouldn't 
that solve the above problem, without using TTL?
   
   I think periodically converting short-term memory to long-term memory is 
certainly a solution. However, we still need to store all the information. Even 
though long-term memory incorporates compression mechanisms, this may still 
lead to inflated memory size. If users are only concerned with recent memories, 
then directly expiring historical data is more reasonable. Therefore, I believe 
that even if such a conversion is possible, a TTL (Time-To-Live) mechanism is 
still necessary.
