Detailed Description

This class implements a partition resolver which routing object is the prefix of a given key.

Delimiter is set by default to '|', still can be changed.

Note
If prefix is not found in the key an IllegalArgumentException is thrown

Examples:

  • Given key "key-1|timestamp", with delimiter '|', the routing object would be "key-1"
  • Given "key-1#DELIM#timestamp", with delimiter '|', then an exception is thrown.
