OBShell-SDK-Python is an SDK provided by theOceanBase Community to facilitate developers with quick access to OBShell services, allowing them to conveniently call OBShell interfaces using this SDK.
pip install obshell
Please ensure that OBShell is running when using it.
Create a specified version client.
from obshell import ClientV1
from obshell.auth import PasswordAuth
def main():
client = ClientV1("11.11.11.1", 2886, PasswordAuth("****"))
Create client_set.
from obshell import ClientSet
from obshell.auth import PasswordAuth
def main():
client = ClientSet("11.11.11.1", 2886, PasswordAuth("****"))
OBShell-SDK-Python provides two types of methods to deploy an OBShell cluster: the first immediately returns after successfully making a request to the OBShell API, and the second waits for the OBShell task to complete after the API request is successful before returning. The former executes the task asynchronously, while the latter executes the task synchronously.
Deploy a 1-1-1 cluster:
- Asynchronous Task Execution
from obshell import ClientSet
from obshell.auth import PasswordAuth
def main():
client = ClientSet("11.11.11.1", 2886, PasswordAuth("****"))
# join master
dag = client.v1.join("11.11.11.1", 2886, "zone1")
client.v1.wait_dag_succeed(dag.generic_id)
# join follower
dag = client.v1.join("11.11.11.2", 2886, "zone2")
client.v1.wait_dag_succeed(dag.generic_id)
dag = client.v1.join("11.11.11.3", 2886, "zone3")
client.v1.wait_dag_succeed(dag.generic_id)
# configure observer
configs = {
"datafile_size": "24G", "log_disk_size": "24G",
"cpu_count": "16", "memory_limit": "16G", "system_memory": "8G",
"enable_syslog_recycle": "true", "enable_syslog_wf": "true"}
dag = client.v1.config_observer(configs, "GLOBAL", [])
client.v1.wait_dag_succeed(dag.generic_id)
# configure obcluster
dag = client.v1.config_obcluster_sync("test-sdk", 11, "****")
client.v1.wait_dag_succeed(dag.generic_id)
# initialize obcluster
dag = client.v1.init_sync()
client.v1.wait_dag_succeed(dag.generic_id)
# get the status of the cluster
status = client.v1.get_status()
print(status)
- Synchronous Task Execution

from obshell.auth import PasswordAuth
def main():
client = ClientSet("11.11.11.1", 2886, PasswordAuth("****"))
# join master
client.v1.join_sync("11.11.11.1", 2886, "zone1")
# join follower

# configure obcluster

# initialize obcluster

# get the status of the cluster
status = client.v1.get_status()
print(status)
Scale out the agent '11.11.11.4' into the cluster where the agent '11.11.11.1' is located.
from obshell import ClientSet
from obshell.auth import PasswordAuth
def main():
client = ClientSet("111.11.11.1", 2886, PasswordAuth("****"))
# scale out
configs = {
"datafile_size": "24G", "log_disk_size": "24G",
"cpu_count": "16", "memory_limit": "16G", "system_memory": "8G",
"enable_syslog_recycle": "true", "enable_syslog_wf": "true"}
client.v1.scale_out_sync("11.11.11.4", 2886, "zone3", configs)
