CRC Properties Configuration
A new property, the queryprocessor.multifacttable property, has been added to the crc.properties file. When this property is set to true the CRC will now look for multiple fact tables. By default, this property is set to false. If you are going to be using multiple fact tables you will need to update this property to be true.
Property: queryprocessor.multifacttable
Value | Behavior |
---|---|
false | The CRC will continue to work as it does in the classic i2b2. Only one fact table (observation_fact) will be queried ("single" mode) |
true | The CRC will work in both modes; single or multiple fact tables. |
Update crc.properties file
1. Open the crc.properties file and scroll to the section called Derived/Multi fact table parameter.
2. Edit the queryprocessor.multifacttable property to tell the CRC to query multiple fact tables.
# Derived/Multi fact table parameter
queryprocessor.multifacttable=true
3. Save your changes and close the file.
Note
If the above parameter does not exist in the crc.properties file, then you have to add it so the CRC can query more than one fact table.
