Large memory spike when collecting metrics

[jay-bhambhani]

Hi there! we've noticed when using the exporter that we have a significant jump in memory consumption when we add it to our airflow image. We understand that this is likely due to the amount of DB querying that the exporter is doing, but wanted to ask if we may have missed something here?

WE are also seeing the same issue , any workaround or suggestions would be greatly appreciated.

Any updates on this? The exporter sidecar is using >8GB all the time. This shouldnt be the case for a container that should simply query the SQL backend.
