📊A distributed counter is a common building block for larger systems and can be used to solve a variety of problems.
📝Designing a distributed counter involves creating endpoints for submitting hits and reading the count.
🛠️The count is stored in a counter data store and can be incremented and read by the user.
What is the basic setup for a distributed counter?
—The basic setup for a distributed counter involves two endpoints: one for submitting hits and another for reading the count. The count is stored in a counter data store.
What can a distributed counter be used for?
—A distributed counter is a common building block for larger systems and can be used to solve a variety of problems, such as rate limiting, flash sales, and inventory management.
How does the user submit hits to the counter?
—The user can submit hits to the counter by sending a request to the 'submit hit' endpoint, which increments the count in the counter data store.
How does the user read the count from the counter?
—The user can read the count from the counter by sending a request to the 'read count' endpoint, which retrieves the count from the counter data store.
Is the distributed counter itempotent?
—No, the distributed counter is not itempotent. Each hit submission will increment the count, and multiple submissions may result in duplicate counts.
