If there are multiple DDLs executed on a table in a short period, extract may need to generate multiple TDRs for the same table within one millisecond. When this occurs, the generated TDRs have the same timestamp.This leads to issue downstream because pump or replicat fails to invalidate the table metadata when needed.
TDR (Table Definition Record) is a definition info of table and columsn, and those are written in trail file.
Multiple DDLs are executed on a table within sub-millisecond apart.
