Open Stack

Hi, all,

I think I understand how does tricircle schedule pods. Based on the flavor
extra_specs or volume extra_specs tags, tricircle queries the pod table for
the records in which resource_affinity_tag is set. Those pods that have the
same key-value pair with extra_specs tag will be selected. Is it correct?

Furthermore, I still have a question mentioned. Do we need to store
historical pod binding records in the pod binding table?

Best regards,
Yipei
