RTL uses full incremental compilation to control memory consumption and you can control the net-change database size to reduce memory consumption.
SQT Memory Consumption Control for RTL
Control the maximum memory consumed by unpacked commands in the DSI SQT cache during transaction profiling in RTL .
Net-Change Database Size
Reduce memory consumption by the net-change database by triggering the net-change database to flush data to the replicate database once the net-change database size reaches a threshold size.
Full Incremental Compilation
Full incremental compilation improves replication performance for real-time loading (RTL) by reducing memory consumption during the processing of large compilable transactions that contain many commands.
