Functions

func InitCSVLog

func InitCSVLog() *csvLog

InitCSVLog initialises a CSVLOG plugin It does this by loading a config file if one can be found. The default filename follows the same convention as the kafka plugin - ie it's in "./plugins/csvlog/csvlogconfig.json" but an environment var - CSVLOGCONFFILE - can be set to provide a different location.

Once the config is set the worker is started

func InitKafka

func InitKafka() *kafka

InitKafka Init kafka client

func LoadCSVLogConfig

func LoadCSVLogConfig() csvBridgeConfig

LoadCSVLogConfig loads the configuration file - it currently looks in "./plugins/csvlog/csvlogconfig.json" (following the example of the default location of the kafka plugin config file) if it doesn't find it there it looks in two further places - the current directory and an "assets" folder under the current directory (This is for compatibility with a couple of deployed) implementations.
