Does like support being distributed to each KV node for computation? Do these three patterns “%21”, “%123%”, and “342%” all support it?

The like function is supported for pushdown.

When using LIKE, if the condition starts with the wildcard %, indexes cannot be used. Pushing down should not be a big problem.

Yes, all three will be issued, it’s just a matter of whether the index is used or not.

The main issue is whether or not to use indexes, not whether or not to push down.

LIKE supports pushdown

Of course it is supported, but it may not necessarily use the index.
