Currently the sharding catalog cache eviction policy is LRU with a hardcoded capacity of 10k entries. There are some improvements we could consider:

- Considering the size of the cached entry, which may vary wildly depending on each collection routing table size.
- Being more aggressive in evicting long-unused entries.
