尽量避免子查询
select y.radish, g.enton
from great g
inner join spaceRadish sr ON sr.greatReferenceID = g.id
inner join super s s.id = sr.springID
inner join experiments e on s.CID = e.analysis
并确保您有正确的索引
table great composite index on (id, enton)
table spaceRadish composite index on (greatReferenceID, springID)
table super cmposite index on (id, cid)
table experiments index on analysis

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.

我必须在查询中用sr.radish替换y.radish，因为y只是临时表的名称。这确实非常快，但没有提供正确的结果，因为存在重复的g.enton实例，而原始查询中就没有这种情况。
编辑：没关系，这是因为订购。谢谢，通过重组，它更快了
