Question about data retention

[Lars-]

Hi,

I love what you did with this data and I am planning to use it in our product. Quick question: how long will data be stored? I am planning to run this on a very low end server with 512MB RAM. Is there a way to limit the maximum memory usage or is this already managed withing the package?

Unfortunately not, as you'll ideally kepp all incoming data until the train has gone. Data about a train service is sent out approximately 5 days before departure and is kept until the train is gone (so 5 days in total). Typical memory usage is around 3600 MB virtual, ~ 780 MB resident memory. A server with only 512 MB would be a bit too scarce on memory.

Thank you for the clear answer. A follow up question in that case: why can I query departures from yesterday? If they are deleted after departure, I should not be able to query them, right?
