Both BigTable and DynamoDB only support eventual consistency. That is a big asterisk in ACID for those technologies.

- why_only_15 3y agoI don't think that's true? Bigtable: https://cloud.google.com/bigtable/docs/replication-overview https://cloud.google.com/bigtable/docs/replication-overview > When using replication, reads and writes to the same cluster are consistent, and between different clusters, reads and writes are eventually consistent. If an instance does not use replication, Bigtable provides strong consistency, because all reads and writes are sent to the same cluster. DynamoDB: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.ReadConsistency.html https://docs.aws.amazon.com/amazondynamodb/latest/developerg... > Both tables and LSIs provide two read consistency options: eventually consistent (default) and strongly consistent reads > Eventually consistent reads are half the cost of strongly consistent reads
