Pleas help me understand the process - memory+CPU that happens in the bckground when I run a code that loads data from a table and stores into QVD.
SELECT * FROM SCHEMA.TABLE;
STORE TABLE into QVD1.qvd;
DROP table TABLE;
How does the memory required vary when data is loaded from TABLE to memory in QVW and written to QVD
If u stored in a table in a QVD then the volume of the table is reduced but not the data ,
QVD are flexible to load data easily in qlikview and run very fast & gives the desired result as soon as possible compare to tables & databases connection......
Qlikview is a in memory tool, so while dealing with large data we make use of this QVD.
This script will import the data from the DB and store it inside the Qlikview with 10x compression.
STORE TABLE into QVD1.qvd; this will store the data inside the Qlikview to Qlikview readable format file called QVD it will be compressed and optimized.
DROP table TABLE; this will delete the data, which is inside the Qlikview application and frees the memory
Did you try monitoring the ram and cpu usage of your workstation or server while reloading a qlikview document with that bit of script? Try asking a local friendly system administrator if you need help with that.
yeah, but I am looking for what happens in terms of memory and Processer usage when these statements are executed
I know what these statements accomplish,
