# Data Transmission Service (DTS): moves and replicates data between databases. "What is Data
# Transmission Service (DTS)" states that it captures ongoing changes using source database logs such
# as the MySQL binary log and the PostgreSQL write-ahead log, that migration starts with a complete
# snapshot before capturing changes, that synchronization is continuous and can be unidirectional or
# bidirectional, and that change tracking captures INSERT, UPDATE and DELETE events in real time and
# exposes them as structured streams.
