Anu Engineer commented on HDDS-293:
-----------------------------------
+1, only thing that is not clear how much memory saving are we looking at? Is
it that we have very large number of keys with single blocks and this patch is
useful in those cases. As I said, I am +1, please feel free to commit. There 2
minor checkStyle issues in the Test file, a white space after ';' in line 58
and line 63, CheckStyle does not like the variable name in caps. Please feel
free to fix them while committing.

> Currently, the field chunks is declared as a List<ChunkInfo> in KeyData as
> shown below.
> {code}
> //KeyData.java
> private List<ContainerProtos.ChunkInfo> chunks;
> {code}
> It is expected that many KeyData objects only have a single chunk. We could
> reduce the memory usage.
