what is the role of mixCoord

[hxlsky]

in my k8s,there is a mixCoord pod,what is its role?

[hxlsky]

is need it to config the flowing nodes:

dataCoord: {}
queryCoord: {}
indexCoord: {}

[yhmo]

mixcoord = rootcoord + querycoord + datacoord + indexcoord

In old milvus versions, you can see one rootcoord, one querycoord, one datacoord, one indexcoord, some data nodes, some query nodes, some index nodes and some proxy nodes in a milvus cluster.
In 2.4/2/5 milvus, you will see one mixcoord, some data nodes, some query nodes, some index nodes and some proxy nodes in a milvus cluster.
