@mukund-thakur i tried using guava LoadingCache, it's not consistently able to evict cache entries, it's doing asynchronously with weak ref and hence leading to inconsistent num of entries. for instance, even when i set max size as 1, i can see 8 entries in the map for more than 15s. hence, maintaining consistency with concurrency seems really problematic with this implementation. there is option to set concurrency too, but still somehow eviction is not frequent enough, i suspect this might be because of this: ``` An update to the map and recording of reads may not be immediately reflected on the algorithm's data structures. ``` -- This is an automated message from the Apache Git Service.
