James Taylor commented on PHOENIX-777: -------------------------------------- I don't think that disambiguates those values from null. I think the idea I floated does, but has some limitations. Another way (possible now) is for an application to reserve a value to mean "null". > Support null value for fixed length ARRAY > ----------------------------------------- > > Key: PHOENIX-777 > URL: https://issues.apache.org/jira/browse/PHOENIX-777 > Project: Phoenix > Issue Type: Task > Reporter: James Taylor > Assignee: Dumindu Buddhika > Fix For: 4.4.0 > > > A null value for a fixed length array can be handled with a bitset tacked on > the end of the array. If an element is set to null, then the bit at that > index is set. Trailing nulls are not stored and an attempt to access an array > past the current size returns null. > Current behavior, > PBinaryArray - Throws an exception when a null is inserted. > PBooleanArray - null is considered as false when a null is inserted. > PCharArray - Throws an exception when a null is inserted. > PDateArray - Throws an exception when a null is inserted. > PDoubleArray - null is considered as 0.0 when a null is inserted. > PFloatArray - null is considered as 0.0 when a null is inserted. > PIntegerArray - null is considered as 0 when a null is inserted. > PLongArray - null is considered as 0 when a null is inserted. > PSmallIntArray - null is considered as 0 when a null is inserted. > PTimeArray - Throws an exception when a null is inserted. > PTimeStampArray - Throws an exception when a null is inserted. > PTinyIntArray - null is considered as 0 when a null is inserted. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
