Parallel asynchronous replication between YDB database instances
In this talk, we present an approach to asynchronous replication in YDB that provides the following characteristics: changefeed from the source database is sharded among multiple persistent queues, sharded changefeed is applied to the target database in a manner that guarantees the target database consistency.
Scalability and Fault Tolerance in YDB
In this talk, we will cover two layers of YDB: Tablet and BlobStorage, which together provide fault tolerance, scalability, and user isolation.
