Re: [google-appengine] Bloom filter index
I've used Bloom filters for a number of purposes, including the scenario you describe - though not on App Engine. Bloom filters are an extremely versatile tool, but are not a panacea. Firstly they aren't as compact as one might expect. By my reckoning, a 1MB bloom filter will accommodate 1M entries with a false positive rate of around 2%. A well implemented trie with a suitable set of keys can approach similar levels of compactness. Secondly, Bloom filters are obviously sensitive to their initial sizing; though they degrade gracefully, in some applications it can be difficult to resize them in-situ without causing unacceptable spikes in throughput. Finally, just in case you hadn't considered it; Bloom filters don't support element removal. This may or may not be an issue for your application. Also, I'm not sure if Brandon's suggestion to consider "Short misses" was targeted at storing more data in the Bloom filter. Bloom filter capacity is independent of key size and smaller keys may result in poorer performance due to weaker hashing. If it's any use I've made an open source Bloom filter implementation available as part of my collections package at http://code.google.com/p/tomgibara/ Tom.

[google-appengine] Re: Remote realtime FIFO implementation
There are two ways to do it. 1. Datastore, optionally memcached. Memcache by itself is not reliable, you will need the Datastore fallback which means everything written to the Memcache has to be written to the Datastore too, so Memcache will probably not improve anything except saving on the Datastore read from Client B 2. Store in Backend Instance RAM. If your traffic is really high, this may become cheaper than using the Datastore. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Re: [google-appengine] Re: Queries that cannot be cursored?
Ah, and there it is documented in the Query docs. However, it would
be very handy if this threw an exception rather than returning null.
Unfortunately, passing in a null Cursor in the fetch options works
just fine - so what happens is that rather than getting an exception
with an explanation of what you are doing wrong, the next query just
continues from the beginning and you get a loop. Oops.

Re: [google-appengine] Re: HRD migration tool now available!
Did you alias your old app id to your new app id? Cause if that is the case, then remote_api is likely talking to the new app (and I don't think it is possible to make it talk to the old app).

Hi Simon, Thanks for the reply; I'm not expecting an automatic migration, I'm just not able to do the manual migration (using the remote_api).

Re: [google-appengine] Attachment in mail

What's the type of "message" in your answer.
Actually, I use this code :
Message msg = new MimeMessage(session);
msg.setDataHandler(new DataHandler(new
ByteArrayDataSource(csv.getBytes(),"text/csv")));
msg.setFileName("data.csv");
msg.setFrom(new InternetAddress("***", ""));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress("",
"info"));
msg.setSubject("Export");
Transport.send(msg);

[google-appengine] Attachment in mail
Hi,
One of my servlet creates CSV content in a String variable.
I'd like to send this CSV like an attachment file but everybody knows
the limitations of GAE : it's impossible to create a file. So, I
decided to find an another solution.
Mine is to attach the CSV string like that :
String csv = "";
Message msg = new MimeMessage(session);
msg.setDataHandler(new DataHandler(new
ByteArrayDataSource(csv.getBytes(),"text/csv")));
msg.setFileName("data.csv");
I receive the mail but without attachment. The CSV string is
integrated into the body part of the mail.
How to attach this CSV string like a CSV file into the mail?
Thanks

Re: [google-appengine] Bloom filter index
Seems like even a 1MB bloom filter (the largest size you can fit in a single entity/memcache bucket) would accomodate an enormously large dataset. The not-so-obvious part is how to update the memcache in sync with the datastore. If you have transactional requirements, you can't update the memcache on datastore write without risking collisions. The answer is to clear the value on write and use CAS operations on read. If you're in Javaland you can use Objectify's CachingAsyncDatastoreService directly with the low-level api. If you're in Pythonland you'll have to implement this yourself... just remember, don't try to update memcache on datastore write. It will fail.

Re: [google-appengine] Remote realtime FIFO implementation
How about this: 1. Rely on an in-memory implementation of FIFO as the primary storage. 2. Store stuff to memcache as a temporary backup to protect against your front-end instances dying because of over-usage of memory, or other reasons. 3. Memcache writes should probably be asynchronous (use taskqueues) to avoid incurring unnecessary latency (I think taskqueue.add is faster, but you should try it out) 4. If your client B doesn't read from the FIFO for some period of time, say 60 seconds, back up your FIFO data into Datastore (asynchronously of course).

Re: [google-appengine] Datastore question
You may also have a slight misconception - the write limit applies to each individual entity, not the entity as a class. So you can only update Thing1 once per second, but you can also update Thing2 once per second, etc. You should have no problem being able to "handle creation of lots of same entities" as long as you don't explicitly put them in a single entity group.

[google-appengine] Re: HRD migration tool now available!
I migrated my app 'bla' to 'bla-hrd' which worked fine. Trying to copy the blobstore failed however. I have 98 blobs in 'bla' and 1 test blob in 'bla-hrd'. Querying both 'bla' and 'bla-hrd' my code always returns 1 blob. It used to return 0 blobinfo when the test blob in 'bla-hrd' wasn't created yet. It seems as if all blobstore access is routed to the new hrd application, making my old blobs unreachable. I also tried using the BlobInfoService (can't remember exact name) with same results. Have a look at the code below and let me know if I missed something or if this is a bug in the migration tool: http://www.copypastecode.com/128643/ -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Intermittent - InvalidSenderError: Unauthorized sender
Browsing through the logs, i noticed the below given error. This happened when the user sending the email is in fact a valid user listed on the app permissions page. Besides that, not all emails hitting that function call fail. So, there has to be a bug on the AppEngine side of things. ** Unauthorized sender Traceback (most recent call last): File "/base/data/home/apps/app_name/app_version/folder/file.py", line 119, in send_page_email message.send() File "/base/python_runtime/python_lib/versions/1/google/appengine/ api/mail.py", line 894, in send raise ERROR_MAP[e.application_error](e.error_detail) InvalidSenderError: Unauthorized sender ** -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
