这使我认为文本列上的普通索引只会加快“ =”查询
通常，文本列上的标准B树索引会加快SARGable查询的速度，例如：
SELECT col FROM tab WHERE col = 'value'
SELECT col FROM tab WHERE col LIKE 'value'
SELECT col FROM tab WHERE col LIKE 'value%'
但不是：
SELECT col FROM tab WHERE col LIKE '%value%';
SELECT col FROM tab WHERE col LIKE '%value';
SELECT col FROM tab WHERE UPPER(col) = 'VALUE';
他们仍然可以从索引扫描中受益，而不是从表中受益，但是它的速度不如索引查找。

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.
