Configuration
caveclient.set_session_defaults(max_retries=3, pool_block=False, pool_maxsize=10, backoff_factor=0.1, backoff_max=120, status_forcelist=(502, 503, 504))
¶
Set global default values to configure how all clients will communicate with servers. Should be done prior to initializing a client.
Note that these values are only used when not set at the client level.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
max_retries
|
int
|
The maximum number of retries each connection should attempt. Set to 0 to fail on the first retry. |
3
|
pool_block
|
bool
|
Whether the connection pool should block for connections. |
False
|
pool_maxsize
|
int
|
The maximum number of connections to save in the pool. |
10
|
backoff_factor
|
Union[float, int]
|
A backoff factor to apply between attempts after the second try (most errors
are resolved immediately by a second try without a delay). The query will sleep
for:
|
0.1
|
backoff_max
|
Union[float, int]
|
The maximum backoff time. |
120
|
status_forcelist
|
Optional[Collection]
|
A set of integer HTTP status codes that we should force a retry on. |
(502, 503, 504)
|
Usage
from caveclient import set_session_defaults
set_session_defaults(
max_retries=5, # would increase the default number of retries
backoff_factor=0.5, # would increase the default backoff factor between retries
backoff_max=240, # would increase the default maximum backoff time
status_forcelist=(502, 503, 504, 505), # would add 505 to the default list
)
set_session_defaults() # would revert all defaults to their original values
Notes
Calling this function will set the default values for all clients created after the call.
Calling this function with any arguments missing will reset that value to the default value.
