About the YCSB+T benchmark

[morcelicaio]

Hi, @ankit-iitb .

I have a question about the implementation of YCSB+T.

Where did you get the latest YCSB+T project?

The only place I can find to fork it is on Akon Dey's github.
https://github.com/akon-dey/YCSB

Could you help me to implement the ycsb+t benchmark correctly?

In his article he reports having such methods:

"
• doTransactionInsert() creates a new account with an
initial balance captured from doTransactionDelete() operation described below.

• doTransactionRead() reads a set of account balances
determined by the key generator.

• doTransactionScan() scans the database given the start
key and the number of records and fetches them from the
data base.

• doTransactionUpdate() reads a record and add $1 from
the balance captured from delete operations to it and write
it back.

• doTransactionDelete() reads an account record, add the
amount to the captured the balance (capture used in
doTransactionInsert()) and then deletes the record.

• doTransactionReadModifyWrite() reads two records,
subtracts $1 from the one of the two and adds $1 to
the other before writing them both back.
"

In the akon repository where I made the fork, I didn't find the implementation of the methods doTransactionInsert() , doTransactionRead() , doTransactionScan() , doTransactionUpdate() and doTransactionDelete().

I just noticed that the doTransactionReadModifyWrite() method is implemented, where it subtracts the value 1 from account A and assigns that value to account B.

Could you help me understand this part of the implementation?
