[Beowulf] Large amounts of data to store and process

[Jonathan Aquilina]

Hi Fred,

I and my colleague had done some research and found an extension for postgresql called timescaleDB, but then upon further research postgres on its own is good for such data as well. The thing is these are not going to be given to use as the data is coming in but in bulk at the end from the parent company.

Have you used postgresql for such type's of data and how has it performed?

Regards,
Jonathan

    Hi Jonathan,
    
    It seems you're collecting metrics and time series data. Perhaps a time series database (TSDB) is an option for you. There are a few of these out there, but I don't have any personal recommendation.
    
    Cheers,
    Fred
