Abstract: Updates performed as part of transaction requests to a data store may be included in a stream of updates. Updates to items in the data store that are included in transactions determined not to be committed to the data store may be excluded from the stream of updates. Records in the stream of updates may include an identifier for the transaction that included the update described by the record. The identifier for the transaction may be used to identify updates to other items in the data store that are included in the same transaction.

Abstract: Transaction requests may be ordered in a distributed database according to an independently assigned sequence. Different distributed system nodes, such as a transaction coordinator and a storage node may independently assign sequence numbers to requests to access a distributed database. A storage node may receive the request from a transaction coordinator with an assigned sequence number and another request to which the storage node may assign a sequence number. The storage node can then order performance of the requests based on the sequence numbers.
