Service Registry¶
1. Description¶
1.1 Model Registry¶
FATE-Flow interacts with FATE-Serving through Apache ZooKeeper. If use_registry
is enabled in the configuration, Flow registers model download URLs with ZooKeeper when it starts, and Serving can get the models through these URLs.
Likewise, Serving registers its own address with ZooKeeper, which Flow will fetch to communicate with. If use_registry
is not enabled, Flow will try to communicate with the set servings
address in the configuration file.
1.2 High Availability¶
FATE-Flow implements automatic discovery of multiple nodes in the same party by registering its own IP and port with Apache ZooKeeper.
2. Configuring the ZooKeeper service¶
zookeeper:
hosts:
- 127.0.0.1:2181
use_acl: false
user: fate
password: fate
