Hello Everyone,
I have a question on Mload & FastLoad.
Lets assume that I have an empty table and I am trying to load a file into this table using Mload or fastload. Now, based on below knowledge, I want to conclude, in application phase , which of these utilities will perform better.
To my knowledge, in Mload, data gets loaded to worktable in aquisition phase and then will be moved to actual table in application phase. My question here is
- Will we have copy of work table on all amps
- Will the parser hash the data from file and then pass the record to worktable on corresponding amp or will it push randomly like in Fastload and then re-distribute in application phase.
In Fastload, data first gets pushed on to the amps in aquisition phase and then in application phase, it gets re-distributed across amps. Does this mean that hashing in fastload happens in application phase and will the data gets moved across amps over BYNET. If this is true, application phase of Fastload takes more time compared to Mload as hashing is involved here.
Please help & correct me if my understanding is wrong
