Package memquota provides a simple in-memory quota implementation. It's trivial to set up, but it has various limitations:
- Obviously, the data set must be able to fit in memory.
- When Mixer crashes/restarts, all quota values are erased. This means this isn't good for allocation quotas although it works well enough for rate limits quotas.
- Since the data is all memory-resident and there isn't any cross-node synchronization, this adapter can't be used in an Istio mixer where a single service can be handled by different mixer instances.
GetInfo returns the Info associated with this adapter implementation.
Limit is implemented by Quota and Override messages.
