Skip Dictionary Encoding Optimization for Integer Type
Starting from Kylin 5, the system supports no dictionary encoding for integer types
With the following settings, optimization of precise deduplication queries can be started:
Build a model that contains precise deduplication metrics
Modify the configuration of the model and add custom settings to the model in the settings interface:
kylin.query.skip-encode-integer-enabled = true
Build the model
Configuration scope
This configuration is only available at the model level
Precautions
- This operation can improve the build performance, if the data hash is serious, it may cause the inflation rate to be too high
- If the value of this parameter changes, you need to re-brush the entire model
