<p>Hi,<br>
in the case of Lucene Queries my main concern is about how to a) properly serialize the query b) how to stream the resusts back, possibly having some pagination / flow control.<br>
I didn't look into hotrod sources, but I was not assuming the hard part would to make it possible to send some new commands?</p>
<p>So if that's all what is needed for transactions to work properly, can't you just add the commands before 5.1?</p>
<p>Cheers,<br>
Sanne</p>
