2534122 - System Replication takeover takes longer than expected SAP HANA

Symptom

In your Disaster Recovery setup you have found the time to complete a takeover takes much longer than expected.

The System Replication Status was 'Active' and in Sync before the primary was disabled and takeover initiated.

Replication from Primary site to Secondary site is with Operation Mode 'logreplay'.

From the service traces on secondary site (those with persistence) the last redo log position before the takeover execution has a timestamp from a long time ago.

For Example:

indexserver_<host>.#####.###.trc

...

[11355]{-1}[-1/-1] < Todays Date and time>i Logger           RecoveryHandlerImpl.cpp(00679) : Redo done up to position: <#######> and time: < (Today date  & time) - n>

...
