HANA Sidecar - Limitations

  • Data must be loaded from current database to HANA database using any of the existing replication scenarios (DXC, Data Services, SLT) or abap custom code
  • If you require real time loading into HANA sidecar you will still need SLT or have custom code that loads to HANA via secondary database connection everytime a change is triggered
  • Custom abap programs are needed to be able to connect to HANA database and retrieve/insert/update data
  • To fully optimize the performance of HANA as sidecar, all custom abap code must be optimized to run SQLSCRIPT in order to fully utilize the HANA calculation (refer to part_2 blog for more details)
  • HANA only runs on SUSE LINUX SP11 so if your current hardware/os does not include SUSE LINUX you will need get hardware specifically for HANA
  • This would mainly improve reporting but not affect the daily performance of your existing transaction system
  • HANA as sidecar using in BW landscape is similar (not the same) to how BWA in current BW landscape works
