Kinesis Data Streams Sizer
Calculate required shards based on hard ingestion limits, and model the exponential cost of Enhanced Fan-Out (EFO).
⚠️ You have 3 consumers. Standard shards cap at 2MB/s read throughput. You will likely experience massive ReadProvisionedThroughputExceeded errors. Enable EFO to model true costs.
