Does OPA support fast loading and dynamic updating

[doaspx]

Hello

I have this scenario. The historical data is very large and needs real-time synchronization.

I understand that real-time synchronization opal can be solved;

So how can we solve this problem? When OPA starts, can it quickly load historical data? Can opal be realized?

Hi @doaspx,

Not sure i fully understand your question, from what i could gather:

• You have a large amount of historical data that you need to load into OPA.
• You want to use OPAL to load this data in real time
  So far so good, OPAL was built exactly for this.

Are you are asking about the speed of loading the data? It depends on the data size, the distance (latency) from the OPAL client to the data sources you fetch the data from and on OPA data loading speed as well. But OPAL is pretty fast and i would wager probably the fastest way to load large amounts of data into OPA from external sources.

The way it works - OPAL will first push a "complete image" of the data when OPA first starts, and then it only pushes incremental delta updates.

Hope it helps, please feel free to ask follow up questions.
