Anu Engineer commented on HDFS-11569:
-------------------------------------
I am worried that we will need to support pagination. Here is the back of
envelop calculation. If we assume users are putting 4 KB sized objects into
ozone and our containers are 5GB in size, then we can have 5GB/4KB objects in a
container, which is
1,250,000. That surely cannot be returned via single RPC call.
Now I do see that you have a filter called "prefix", but then again user may
not know how many keys with that prefix exists and may not be able to deal with
the list without pagination.

> List keys by prefix from a container. This doesn't need to support pagination
> as keys in a single container should be containable.
