A method for change data capture state tracking includes accessing a distributed database including a plurality of clusters, each cluster of the plurality of clusters including a respective plurality of partitions, each cluster of the plurality of clusters configured to receive read and write operation. The method includes receiving, at a second cluster, a plurality of changes for a second table and storing the plurality of changes at a replication log. The method also includes asynchronously replicating the plurality of changes from the second table to a first table and maintaining a respective change stream position tracking a respective position in the replication log indicating one or more changes of the plurality of changes that have been replicated. The method includes receiving a read request at the first cluster requesting one or more rows of the first table and returning the respective change stream position.
