in_memory Feature Class field size limits

WesMiller

I can find feature class limits for a file geodatabase feature class here ArcGIS Desktop  does any know where to find the information\limits for an in_memory feature class. I'm currently looking to find the maximum text field size, I would also like an overview of the limits of the in_memory feature class.

It appears as though the only limitation is you computer's memory.  Interestingly, the in_memory feature class appears to ignore the defined length for fields. I the following script I created set a field length to 5, the successfully appends a record with a field length of one million.  When I updated the record to 1 billion, i got a memory error.

import arcpy
testFC = arcpy.CreateFeatureclass_management(r'in_memory','testFC', 'POLYGON', "", "", "", arcpy.SpatialReference(32100))
arcpy.AddField_management(testFC,'COMMENT',"TEXT","","",5)

ic = arcpy.da.InsertCursor(testFC,('COMMENT'))
ic.insertRow(('test1',))
ic.insertRow(('t'*1000000,))
del ic

with arcpy.da.SearchCursor(testFC,('COMMENT')) as c:
    for row in c:
        print len(row[0])
