[workers.runtime.connection]
Settings
max_in_flight
Limits how many worker-control requests can be waiting for replies on one connection.
- Default:
64
- Type: integer; positive
Example
64 allows up to 64 unfinished requests on that connection. This controls requests such as task assignment, not the number of SQL rows returned.
max_message_bytes
Limits the size of one request or reply sent over a worker-control connection.
- Default:
68157440
- Type: integer (bytes); positive
Example
68157440 allows a control message up to 65 MiB. A task assignment must fit this limit even if the worker has enough memory to execute it.
response_timeout
Sets how long the caller waits for a reply to a worker-control request.
- Default:
30 s
- Type: duration
Example
{ secs = 30, nanos = 0 } allows 30 seconds for the control reply. A query may keep running after this wait ends; its execution deadline is a separate setting.
