[google-appengine] Re: Google Datastore can't allow to add entities having value more than 150 characters .

[Chirag Parmar]

Thanks for the reply  .
 
I am adding entity to datastore . Each entity's key and value are  
java.lang.String . But when length of value exceed 150 characters it gives 
me 500 internal server error.  
But thanks Vinny P for suggestion ,wrapping using Text object works for me. 

Please have a look at my concept, I have created a prototype of it.

Hi Chirag,

Do you mean a String as a property of the Entity or as the key name? 

If you mean String as a property, then I'm not sure where you're getting 
the 150 char limit. The datastore limits string properties to 500 chars 
(see 
https://developers.google.com/appengine/docs/java/datastore/entities#Properties_and_Value_Types
 ). 
There should be more space than just 150 characters. What you can do is to 
try wrapping the String in a Text object (text objects are capped at 1 MB 
in size, although they are not indexed). See the documentation here: 
https://developers.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/Text

If you mean the key name, you don't need a 150 character long key name. 
Instead, try using a MD5 or SHA1 hash on your long key names, then using 
the hash as the key name.
