示例使用id列作为连接键。
下推连接键可用于索引下推或位向量下推。
The pushed-down join keys can be used in an index pushdown or a bit-vector push-down.
性能的提高取决于连接键被下推时所在维度表的过滤选择度。
The performance improvement depends on the selectivity of the filter on the dimension table from which the join keys are pushed down.
That doesn't heal naturally but can be reformed by other enzymes called ligases, ligases re-established the phosphate bonds.
这不能恢复如初,但用连接酶可以做到这一点,连接酶能重建磷酸键
So if I try to rotate my 2 atoms, you see that I have to break that pi bond, because they need to be lined up so that the electron density can overlap.
如果我要试着转动两个原子,你会看到我必须要打破一个π键,因为他们需要连接起来,让那些电子能够重叠。
The IgM is really five IgG-type molecules that are linked together through disulfide bonds, such that their FC portions are all pointing in and their antibody binding portions are all pointing out.
gM是由五个IgG分子组成的,IgG分子之间通过二硫键连接,免疫球蛋白尾部的FC片段都指向内侧,而抗体的抗原结合位点都指向外侧
