Ruleset Management

The eKuiper rule command line tools allows to import and export all the stream and rule configurations.

Ruleset Format

The file format for importing and exporting ruleset is JSON, which can contain three parts: streams, tables and rules. Each type holds the the key-value pair of the name and the creation statement. In the following example file, we define a stream and two rules.

{
    "streams": {
        "demo": "CREATE STREAM demo () WITH (DATASOURCE=\"users\", FORMAT=\"JSON\")"
    },
    "tables": {},
    "rules": {
        "rule1": "{\"id\": \"rule1\",\"sql\": \"SELECT * FROM demo\",\"actions\": [{\"log\": {}}]}",
        "rule2": "{\"id\": \"rule2\",\"sql\": \"SELECT * FROM demo\",\"actions\": [{  \"log\": {}}]}"
    }
}

Import Ruleset

This command accepts the ruleset and imports it into the system. If a stream or rule in the ruleset already exists, it is not created. The imported rules are started immediately. The command returns text about the number of streams and rules created

# bin/kuiper import ruleset -f myrules.json

Export Ruleset

This command exports the ruleset to the specified file. The command returns text about the number of streams and rules exported.

# bin/kuiper export ruleset myrules.json
