gnat_merge

Synopsis​

Merges Parquet files into designated time intervals.

Description​

The gnat_merge tool is primarily used to merge streams. This tool implements the gnat command line interface and shares the same required and optional arguments as other GNAT tools.

Required Arguments​

--input <merge_configuration>​

The --input argument specifies the input configuration file in JSON format.

Json File Format​

The JSON file is composed of an array of JSON objects, each object representing an input path.

Example​

Merge files from /var/spool/icmp, /var/spool/udp, /var/spool/tcp into one stream sending results to /var/spool/merged every minute

$ gnat_merge --input /etc/merge.json --output /var/spool/merged --interval minute

The configuration merge.json file should be in JSON format and specify input directories. Here is an example configuration file:

[
    { "input":"/var/spool/icmp"},
    { "input":"/var/spool/tcp"},
    { "input":"/var/spool/udp"}
]
