Log upload | |
| |
| The maximum size of a single value within a log entry is 1 MB. |
| The total size of all Values within the logGroup section of a protobuf package must not exceed 5 MB. |
| Keys in Log cannot be the following reserved fields and cannot start with __FILENAME__, __TIMESTAMP__, __LOGSETID__ and __TOPICID__. |
| The total size of the request body for a single upload should not exceed 6 MB before compression. |
Frequency control | The write request limit for a single topic partition: 500 QPS. If this limit is exceeded, the system will return status code 429, indicating the error "SpeedQuotaExceed." During periods of high write frequency, it is recommended to split the topic partition. Note: Here, 500 QPS does not equate to 500 log entries per second. A single protobuf package from one request may include multiple log entries for batch upload. |
| |
Traffic throttling | Write throughput limit for a single topic partition after compression: 5 MB/s. If this limit is exceeded, the system will return status code 429, indicating the error "SpeedQuotaExceed." During periods of high write throughput, it is recommended to split the topic partition. |
