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

I don't think that's true?

Bigtable: 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/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
