Change tracking - sys.dm_tran_commit_table
Applies to: 
SQL Server
Azure SQL Database
Azure SQL Managed Instance
Azure Synapse Analytics
Analytics Platform System (PDW)
Displays one row for each transaction that is committed for a table that is tracked by SQL Server change tracking. The sys.dm_tran_commit_table management view, which is provided for supportability purposes and exposes the transaction-related information that change tracking stores in the sys.syscommittab system table. The sys.syscommittab table provides an efficient persistent mapping from a database-specific transaction ID to the transaction's commit log sequence number (LSN) and commit timestamp. The data that is stored in the sys.syscommittab table and exposed in this management view is subject to cleanup according to the retention period specified when change tracking was configured.

Note
The table sys.dm_tran_commit_table will not reflect live changes for read-only users, as VIEW SERVER STATE permission is required. The changes remain stored in the rowstore until a CHECKPOINT occurs, following which read-only users will see them reflected. This behaviour isn't observed for SA users.
