Java: Use functions/stored procedures for calculating similarity

The implementation of the memory nearest match API computes cosine similarity on the client side.
Is it possible to compute cosine similarity on the database side through a database function or stored procedure?
If so, withEmbeddings could be pushed to the database side (i.e., should the embeddings column be selected?)

• Could sorting and limiting be done on the database side, too?
• Is the extra overhead on the database a good tradeoff for less overhead in data on the wire?

从 memory nearest match API 及其 withEmbeddings 行为入手。调查当前如何处理 cosine similarity、排序和限制，然后评估是否可以通过数据库函数或存储过程将这部分工作移到数据库中。该 issue 没有定义具体的实现或完成标准。
