Getting size in bytes of a zarr group

[aliaksei-chareshneu]

Dear all,

Could you tell me please if it is possible to get size of a zarr group in bytes?

Thank you for any input,

do you want the size of the group metadata in bytes (generally small, because it's JSON), or the size of all the group + arrays stored inside that group, in bytes (potentially very large, depending on the number of arrays and how big they are)

[aliaksei-chareshneu]

Thank you for the response. The second option - size of all the group + arrays + subgroups - anything that is inside that group, recursively.

the getsize method defined on the store class (accessed via group.store) should do this. But I imagine this could take a long time to run, if you have arrays with many chunks

Thank you very much. However, it looks like it does not take into acoount multiple nested groups. Is it possible to do in case there are multiple nested groups?
