Hi, as I need to use new Ubuntu OS, I need to update my Couchbase server version to >7. Hence some older projects which were using Java SDK version 1.x will no longer be working.
Now I’m trying to update the projects to use Java SDK version 3.x. However, I found some data having “flags=2” and “type=base64”, these data were strings with large size.
I’m trying to call “get()” on these data, but I got byte array which cannot be converted to original data (tried “new String(b)”).
May I know how can I parse these kind of data back to string?
Thanks a lot!
Hi @littlewitchanita ,
The “flags=2” and the fact that you’re upgrading from Couchbase SDK 1.x makes me suspect the document was created using a legacy transcoder that used GZIP compression.
If you know in advance the document was written using the legacy transcoder, you can read it like this:
GetResult result = collection.get(
String content = result.contentAs(String.class);
(More info about how to use transcoders in SDK 3: Transcoders & Non-JSON Documents | Couchbase Docs)
Alternatively, you could read the document as a byte array (without Sdk2CompatibleLegacyTranscoder), then un-gzip the byte array yourself and pass the result to the String constructor.
It works, thanks very much.
Now I can continue on updating the SDK.
