How can milvus release deleted collection in memory?

Question

1. When calling the drop_collection() to delete a table, why is memory not released?

2. How could milvus free up the memory space occupied by the deleted collection?

Answer 1

• Because Milvus uses LRU caching strategy, memory occupied by deleted collection doesn't be released immediately.
• Deleted data in memory could be replaced by new data when the cache is full. Otherwise, you could try to restart Milvus to free up memory.
