file-instance.xml: All components (parser, sink, store) have chosen the file-based persistence mode. Note that HA mechanism is not supported; Features: Stand-alone persistence is supported; Scenario: Production environment, no high-availability cluster requirements, Simple and usable.
default-instance.xml: All components (parser, sink, store) have selected persistence mode. At present, the main way of persistence is to write to zookeeper to ensure data cluster sharing; Features: Support high-availability clusters; Scenarios : Production environment, clustered deployment ( if file-instance.xml is used, canal will generate a meta.dat file after reading binlog to record the location information currently read to binlog ).
