Hello, from 2.5.4 release notes, it is mentioned that support milvus support 1m partitions. By 2.5.5 release notes, it is mentioned that it fully support 100k partitions. Why did it decrease? Is this a typo?

I guess 100K is safe. 1M is too much too now, we are still working on it

@xiaofan-luan Could you please share some test details which has been done internally to certify this number?

There are 2 tests we ran to test for this improvememt

1. having 150k+ collections with default partitions
2. having 150 collections with 1k partitions for each collections
   Both tests can run successfully in a Milvus cluster, some tips for this cluster:
3. it is better to have a 8c32g mixCoord
4. it is better to have a etcd cluster with 2c8g each pod

Moreover, 1m partitions is our next target that we are working on.
