Re: [Bigdata-developers] [Blazegraph] First somewhat amusing trial on blueprints

[Brad B. <be...@sy...>]

Jack,

I saw Bryan's note regarding data to replicate the issue.  That would
definitely be helpful.  Regarding the journal size, the journal makes an
initial allocation upon creation, which is configurable, and then fills it
up over time.  That is likely the explanation for the large initial size.

Thanks, --Brad
