…mpression This PR allows measurements with the same name and type to have different encoding and compression types during TsFile loading. Previously, duplicate measurements would throw an exception. Now, if measurements have the same name and type but different encoding/compression, they will be deduplicated by keeping only one schema entry. Changes: - Add updateDevice2TimeSeries method in LoadTsFileTreeSchemaCache to support updating the device-to-timeseries mapping - Modify makeSureNoDuplicatedMeasurementsInDevices in TreeSchemaAutoCreatorAndVerifier to allow same measurement with different encoding/compression by deduplicating instead of throwing an exception - Only throw exception when duplicate measurements have different data types
