SLT
Concept-trigger based.
DB triggers
controls delta mechanism involved in it.
Logging
table records the data record last loaded and this helps with delta working
properly during SLT.
Read module
pushes data in to replication server,
If any
transformation needed it will be handled by transformation engine and write
engines pushes that to application tables in SAP HANA.
Hope this
helps understand the Trigger based approach
