The Qlik Replicate administrator adds a new column to one of the tables in a task

What should the administrator do to replicate this change?

Show Suggested Answer Hide Answer
Suggested Answer: C

To run a Qlik Replicate Task at a high-performance level, the main hardware components that are recommended include:

Cores: A higher number of cores is beneficial for handling many tasks running in parallel and for prioritizing full-load performance1.

SSD (Solid State Drive): SSDs are recommended for optimal performance, especially when using a file-based target or dealing with long-running source transactions that may not fit into memory1.

Network bandwidth: Adequate network bandwidth is crucial to handle the data transfer requirements, with 1 Gbps for basic systems and 10 Gbps for larger systems being recommended1.

The other options do not encompass all the recommended hardware components for high-performance levels in Qlik Replicate tasks:

A . SSD, RAM: While these are important, they do not include the network bandwidth component.

B . Cores, RAM: This option omits the SSD, which is important for disk performance.

D . RAM, Network bandwidth: This option leaves out the cores, which are essential for processing power.

For detailed hardware recommendations for different scales of Qlik Replicate systems, you can refer to the official Qlik documentation on Recommended Hardware Configuration.

I'd go with C. Who has time to stop and resume the task every time a column is added? Ain't nobody got time for that!

D? Really? Stopping and reloading the entire task sounds like a nuclear option. Let's keep it simple with C.

I see your point, but I still think C is the safer choice in this situation.

But wouldn't stopping and resuming the task be quicker? I'm leaning towards A.

I think C is the best option here. Changing the DDL Handling Policy should do the trick.

I'm torn between B and C. Enabling the __CT tables might be a bit overkill, but it could cover all bases. Decisions, decisions.

Yeah, that sounds like a safer option than enabling __CT tables.
