SAP vaadu konni samvatsarala kritam BWA(BIA) ane oka appliance introduce chesaadu .. Adi SAP BW ki connect autundi .. Pure In Memory Appliance .. ni Disk I/O anamaata .. BW nundi data ni BWA ki load chestam .. Users Quesries BWA meeda run chestaaru .. Disk Latency undadu .. I/O undadu kabatti chaala speed ga results vachevi ..

Appudu vachina aalochana .. why only some of Data / why not all data in memory ani ..

[Joey_Tribbiani]

BWA kuda columnar storage ni vaadukuntundi ..

Ante table ni row by row kakunda .. column by column store chestundi .. Deenivalla Selects chaala quick ga autai .. updates/inserts Slow ne .. Kaani BWA lo updates em undav kada .. Just reads ee !!

So inka vishayaaniki vaste .. Hard Ware innovations ...

Memory became in-expensive .. Multicore processors ..

So data ni Disk lo pettadam kante memory lo pettadam valla speed ga access autundi .. and multi core processors .. Computation & massive parallel processing enable autundi ..

Data in main memory can be accessed more than a hundred
thousand times faster than data on a spinning hard disk, and even flash technology storage is
about a thousand times slower than main memory. Main memory is connected directly to the
processors through a very high-speed bus, whereas hard disks are connected through a
chain of buses (QPI, PCIe, SAN) and controllers (I/O hub, RAID controller or SAN adapter,
and storage controller)

yes they do have ... with design approches ani cheppaaa chudu ....... HP vadi latest servers use mongoDB with in memory process ......

SAP hana ichee extraa enti?????
