Overview
The vector servers can be deployed alongside Ultipa Powerhouse (v5), providing support for vector indexing and search.
Showing Vector Servers
Retrieves information about all vector servers:
show().vector()
Retrieves information about the vector server named vector_server_1:
show().vector("vector_server_1")
The information about vector servers is organized into a table named _vector, including the following fields:
Field |
Description |
|---|---|
name |
Name of the vector server. |
addr |
IP address and port of the vector server. |
status |
Current state of the vector server, which can be ACTIVE or DEAD. |
last_heartbeat |
Timestamp of the last heartbeat sent to the meta servers by the vector server. |
Adding a Vector Server
After successfully deploying a new vector server, it must be registered with the meta servers using the alter().vector().add() statement before it can be utilized. This process ensures that the new vector server is recognized within the system.
The following example adds a vector server with the name vector_server_1 and the address 127.0.0.1:55555:
alter().vector().add({name: "vector_server_1", addr: "127.0.0.1:55555"})
Deleting a Vector Server
You can unregister an inactive or obsolete vector server from the meta servers using the alter().vector().delete() statement.
The following example deletes the vector server with the name vector_server_1:
alter().vector().delete({name: "vector_server_1"})
