Hi all, I am trying to use BinaryObject to support data of different class definitions in one cache. This is for my system upgrade. I first start a cache with data, and then launch a new node to join the cluster and put new data into the existing cache. The new data has a different class definition. I use the same class name, but add a member to the class. I can add the objects of this new class to the cache. The cache size changes and I can get both the new and old data using keys. However, when I use SQLFieldsQuery like "select id from myclassname" where id is a member exists in both the versions of classes, I can get only the old data. There is no error or exception. SQL just cannot find the data of the new class definition.
How can I use SQL queries to find both the new and old data? The new data is in the cache, but it seems not being in the table using my class name. Where is the new data? Is there a new table? If yes, what is the table name? I do not expect to see the new column using the old query. I just hope to see the old fields of new data using the old queries. BTW, I use QueryEntity to set up fields and indexes in my codes. Does anyone has an example about how to add fields to existing cache dynamically? Thank you!
