The only issue is with indexing and access patterns.
When tweets are stored individually they can be retrieved
by queries referring to individual metadata.
This unfortunately is costly.
So the question remains, is it OK to retrieve whole sets
of tweets compressed together into a Blob in Entity?
I have full-text indexed all of O'Reilly eBooks (1,600 of them) using
my own search engine. You can see how the search works if you have an
Android tablet and install (free app) eCarrel (O'Reilly bookstore). To

XSLT is not a parser, but a language to express XML transformations.
2 questions:
1) why do you need XSLT in your app?
2) do you need high performance? Here I can help w/ software.
As to StreamSource, you have other constructors for it,
not necessarily using Files!

then persist a Blob wrapper around resulting byte array

You need to read your Blob's content in several chunks
that are no larger than the limit.
Combining this with XML file compression can also make sense.

An important reason for my making the images smaller is to reduce
