Subject: Strategy for changing fields in a class serialized with PDX
Cluster configuration [1] is currently serialized with PDX and stored in an
internal region that is replicated on all Locators. I would like to change the
Configuration class from having
That Configuration class implements DataSerializable, not PdxSerializable.
FYI the PdxReader does have a method to check if a field is present.
The way to handle different versions of geode with DataSerializable is to
use the versioning support described on this page -
https://cwiki.apache.org/co
One more option would be, by taking advantage of PDX versioning
support...The PDX mechanism can handle multiple versions of the same class,
instead of modifying the existing field, you could add a new field with Map
typeWhen new locator (with new pdx version) reads the old
configuration, it con
Jared,
I meant the server/product version number, if it was stored as part of the
ClusterConfig definition in the pdx...If its not, we could think about
adding one, which could help in the future to identify the version of the
cluster configuration saved/created.

Anil - The class does have a serialVersionUID defined, if that’s the type of
version number you mean. But the serialVersionUID is not explicitly written
out by the toData() method of the class. Could you point me to any examples in
the code of checking the version number on a PDX serialized ins
You can use version numbers, if its available...
We use this mechanism in many cases, rolling upgrade(?), Server to client
communication...

Cluster configuration [1] is currently serialized with PDX and stored in an
internal region that is replicated on all Locators. I would like to change the
Configuration class from having a Set jarNames to having a Map jarNamesToJarBytes. However, this would create a problem when a
Locator runn
