Build zero-downtime write architectures for Amazon Neptune
A detailed guide on building zero-downtime write architectures for Amazon Neptune using a write queue pattern. By placing a durable message queue (SQS, Kinesis Data Streams, or MSK) between the application and Neptune, writes are accepted continuously even during maintenance windows, failovers, and scaling operations. The post covers causes of Neptune write unavailability, how the queue pattern works, tradeoffs (eventual consistency, operational complexity, cost), a comparison table for choosing between SQS Standard/FIFO, KDS, and MSK, idempotency strategies using Gremlin mergeV()/mergeE() or openCypher MERGE, ordering options, monitoring with CloudWatch, read-after-write consistency strategies, and multi-Region deployment considerations with Neptune global databases.
