Much calls to Datastore

[labgua]

Hi @UltimaPhoenix

First, i want congratulate with you for your work.
I'm new to Lucene but for some requirements I must use it.

Trying your GaeDirectory, I noticed there are much calls to the datastore, as I see too in the tool Trace .
But I state that I do not use it to index directly Documents (as i seen in the web, unless the big frameworks like Hibernate Search). When there is the need i use a mapper that converts the entity in an opportune Document.

There is a way to "buffering" the calls to the datastore to speed up the operations with Lucene? Or are there technological limitations that can not be exceeded?
Would you have advice for me?

Hello, thank you for using lucene appengine. Yes you're right LAE use the datastore as much as Lucene uses filesystem to index files (and few other things). This project doesn't contain any facility to do buffered indexing and it's demanded to the user to build that. You can take a look at other considerations here.

Thank You for your response.
Yes, I will have to see what happens moving the computation in Task Queue ( also because it need much time ).
I don't like Google API Search, unless the price, because I think that a document must not have max size to 1MB : this does not improve the performace on large quantity of data.
As I can undestand on the web, the problem isn't related to the space but to the working frequency, Exactly as you say the same.
Calls unfortunately are so many and of what I am worried. But this is the reason why there are cloud.
