ReleasePartitions()

This method releases partition(s) of the specified collection from memory.

Invocation

client.ReleasePartition(ctx, collName, partNames)

Parameters

Parameter	Description	Type
ctx	Context to control API invocation process	context.Context
collName	Name of the collection to release partitions from	String
partNames	List of names of the partitions to release	Slice of string

Constraints

• Error will be returned at the attempt to load partition(s) when the parent collection is already loaded. Future releases will support releasing partitions from a loaded collection, and (if needed) then loading some other partition(s).
• “Load successfully” will be returned at the attempt to load the collection that is already loaded.
• Error will be returned at the attempt to load the collection when the child partition(s) is/are already loaded. Future releases will support loading the collection when some of its partitions are already loaded.
• Loading different partitions in a same collection via separate RPCs is not allowed.

Return

No return.

• ErrClientNotReady, error that the client is not connected.

• ErrCollectionNotExists, error that the collection with the specified name does not exist.

err := milvusClient.ReleasePartitions(
  context.Background(),

)
if err != nil {
  log.Fatal("failed to release partitions:", err.Error())
}
