Storage Analytics buffers log messages internally after which you can periodically updates the suitable blob or makes a different a single with the latest batch of log entries. This lowers the volume of writes it ought to complete to the blob provider. For anyone who is utilizing a similar Answer in your own personal software, it's essential to look at how to deal with the trade-off concerning dependability (writing every single log entry to blob storage because it transpires) and price and scalability (buffering updates with your application and producing them to blob storage in batches). Concerns and issues
