'What does rotate period, bufferlogsize, and synctimeout mean exactly in Winston Azur blob storage? Explanation with simple examples are appreciated

In our project we are using winston3-azureblob-transport NPM package to store Application logs to blob storage. However due to increase in users we are getting an error "409 - ClientOtherError - BlockCountExceedsLimit|The committed block count cannot exceed the maximum limit of 50,000 blocks".

Could anyone tell us using rotatePeriod, bufferLogSize and syncTimeout helps us to stop the error "409 - ClientOtherError - BlockCountExceedsLimit|The committed block count cannot exceed the maximum limit of 50,000 blocks".

Also provide any another alternative solution. However Winston logger should not be replaced.

The error "The committed block count cannot exceed the maximum limit of 50,000 blocks" usually occurs when the maximum limits are exceeded.

Each block in a block blob can be a different size. Based on the Service version you are using, maximum blob size differs.

If you attempt to upload a block that is larger than maximum limit your service version is supporting, the service returns status code 409(ClientOtherError - BlockCountExceedsLimit). The service also returns additional information about the error in the response, including the maximum block size permitted in bytes.

  • rotatePeriod: A moment format ex : YYYY-MM-DD will generate blobName.2022.03.29
  • bufferLogSize: A minimum number of logs before sync the blob, set to 1 if you want sync at each log.
  • syncTimeout: The maximum time between two sync, set to zero if you don't want.
