Description
queue_paging_uplimit
This variable controls:
- The max integral value of the URI parameter "limit" a client can use in a Marconi/specs/api/v1#List Queues request URI, thus, the maximum number of queues a client can list one time. The default value is 20, which means, a request like the following:
GET /v1/queues?limit=30
will result in a 400 Bad Request response.
message_paging_uplimit
This variable controls the following API limits:
- The maximum items a client can put in a Marconi/specs/api/v1#Post Message(s) request's JSON array, thus, the maximum number of messages a client can post one time. The default value is 20, which means, a request like the following:
POST /v1/queues/noein/messages HTTP/1.1 Host: marconi.example.com ... [ { "ttl": 300, "body": "msg1" }, { "ttl": 300, "body": "msg2" }, ... { "ttl": 300, "body": "msg21" } ]
will result in a 400 Bad Request response without any message to be posted.
- The max integral value of the URI parameter "limit" in a Marconi/specs/api/v1#List Messages request URI, thus, the maximum number of messages a client can list one time. The default value is 20, which means, a request like the following:
GET /v1/queues/noein/messages?limit=21
will result in a 400 Bad Request response.
- The max integral value of the URI parameter "limit" in a Marconi/specs/api/v1#Claim Messages request URI, thus, the maximum number of messages a client can claim one time. The default value is 20, which means, a request like the following:
POST /v1/queues/noein/claims?limit=22 Content-Type: application/json ...
will result in a 400 Bad Request response.
- The maximum number of message IDs allowed for the URI parameter "ids" in a Marconi/specs/api/v1#Get a Set of Messages by ID request URI, thus, the maximum number of messages a client can fetch one time in a bulk getting. Note that although this is not a paging API, the URI is usually returned in a message posting's "Location" header. The default value is 20, which means, a request like the following:
GET /v1/queues/{queue_name}/messages?ids=msg1,msg2,...,msg21
will result in a 400 Bad Request response.
- The maximum number of message IDs allowed for the URI parameter "ids" in a Marconi/specs/api/v1#Delete a Set of Messages by ID request URI, thus, the maximum number of messages a client can delete one time in a bulk deletion. Note that although this is not a paging API, the URI is usually returned in a message posting's "Location" header. The default value is 20, which means, a request like the following:
DELETE /v1/queues/{queue_name}/messages?ids=msg1,msg2,...,msg21
will result in a 400 Bad Request response.
message_ttl_max
This variable controls:
- The maximum integral value of the "ttl" fields allowed for each message in a Marconi/specs/api/v1#Post Message(s) request, thus, the longest time (in seconds) a message can possibly live without being claimed. Note that the minimum TTL is 60s. The default maximum is 1209600s, 14 days. Which means, a request like the following:
POST /v1/queues/noein/messages HTTP/1.1 Host: marconi.example.com ... [ { "ttl": 300, "body": "msg1" }, { "ttl": 1300000, "body": "msg2" }, ... { "ttl": 300, "body": "msg10" } ]
will result in a 400 Bad Request response without any message to be posted.
claim_ttl_max
This variable controls the following API limits:
- The maximum integral value of the "ttl" fields allowed in a Marconi/specs/api/v1#Claim Messages request, thus, the longest time (in seconds) a claim can possibly live without being claimed. Note that the minimum TTL is 60s. The default maximum is 43200s, 12 days. A request like the following:
POST /v1/queues/noein/claims Content-Type: application/json ... { "ttl": 50, "grace": 60 }
will result in a 400 Bad Request response.
