  Why? ✅ Problem Root Cause: Kinesis Data Streams with default settings may have insufficient shards to handle the incoming data rate. Each shard supports 1 MB/s input and 2 MB/s output. If exceeded, data is throttled or lost. ✅ Solution: Increase shard count to match the data throughput. Calculate required shards: text Number of shards = (Total data input rate in MB/s) ÷ 1 Example: If the app sends 5 MB/s, use at least 5 shards.

  C. Atualizar o número de fragmentos do Kinesis: Aumentar o número de fragmentos melhora a capacidade de processamento e a taxa de transferência do stream. No entanto, este não é o problema aqui, pois a perda de dados ocorre devido ao período de retenção insuficiente, e não devido a limitações de capacidade.
