[jboss-dev-forums] [Design of JBossCache] - String size limitations with TreeCacheMarshaller

See http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3968346 and JBCACHE-756. The story is that Strings are written using writeUTF() which has a 65535 byte limit. See: http://java.sun.com/j2se/1.5.0/docs/api/java/io/DataOutput.html#writeUTF(... While I initially thought that fixing this would: 1) Involve having to write String objects directly (inefficient) as any other form of writing a byte stream will result in hitting some limit or the other. 2) Break binary stream compat with the 1.4 series. I've expressed these in the JIRA task. Thinking about this a bit more, 1) Perhaps we can chunk Strings into several writeUTF() calls. 2 bytes can be written first, to identify how many chunks to expect. This will give us a limit of 2^16 x 2^16 bytes, or 4GB of String data (!). 2) We can make this backward-compatible by using the current format for Strings under 64kb, and a new magic number (MAGIC_NUMBER_LARGE_STRING ?) for a 'chunked' version, up to 4GB Strings.
