Noble Paul commented on SOLR-13347:
-----------------------------------
I would like to know if the patch I just submitted fix the problem. If it does
not , we will see investigate this further.
Let me explain why adding new types is a problem
JavabinCodec is a public format using which users can send data to Solr.
Whereas TransactionLog is something Solr internally uses. When we add a new
type to JavabinCodec,
* it is a backward incompatible change. (new clients can't talk to old Solr )
* It also creates problems with compatibility with other formats. i.e. I cans
send a UUID using native format using javabin, but when I'm using json/XML it
has to use String. This requires special handling in Solr to handle data that
is coming in as native object vs. String. So, we are introducing special cases
everywhere
I'm OK with having a new type if it is limited to TransactionLog because it is
used internally only. We can do whatever we want .
