@tonyespy This issue aims to support your original idea which wll not need a helper applications after it is implemented. The kuiper CLI client do supporte `-f` to specify a...

Not fixed in 1.3.1 due to test fails. Move back to the backlog.

I don't think RuleRegistry is the obstacle of stateless. The rule content itself is already stored in external KV, check [RuleProcessor in xsql_processor.go](https://github.com/emqx/kuiper/blob/master/xsql/processors/xsql_processor.go). [RuleRegistry](https://github.com/emqx/kuiper/blob/c14dbd254eccf79b030d4373e1d3896aabc340d1/xstream/server/server/ruleManager.go#L25) serves a different purpose to hold...

I think this is a good idea to allow specifying if a column is nullable. We will prioritize this, thanks.

@RBrothersBSI After v1.3.1, the [strictValidation=false](https://github.com/lf-edge/ekuiper/blob/master/docs/en_US/sqls/streams.md#strict-validation) will take effect and set default values for null values so that you can pass in partial properties. Does this work for you

@bighb69738 I don't think we directly use those, maybe they are imported by the dependencies. Where do you run the scan and do you have more information where do these...

Thank you, I think we need to upgrade the base alpine version.

What version do you use? Any findings in the log?

Please modify the join to have `on` as early as possible such as: ```SQL cz110201Double_MB1_cz110201Double_MB10016 left join cz110201Double_MB1_cz110201Double_MB10015 on cz110201Double_MB1_cz110201Double_MB10016.Data[0]->AssetCode = cz110201Double_MB1_cz110201Double_MB10015.Data[0]->AssetCode left join cz110201Double_MB1_cz110201Double_MB10014 ON cz110201Double_MB1_cz110201Double_MB10016.Data[0]->AssetCode = cz110201Double_MB1_cz110201Double_MB10014.Data[0]->AssetCode ```

The data is too much to return if your on condition does not filter much data or even no on condition, the result data will be n * n *...
