An Efficient Data Analysis Framework for Online Security Processing

Algorithm 1

The total execution procedure of LCN-Index.
Input: query set Q, stream S
Step 1: partition Q into a batch of predicate sets P.
Step 2: building interval indexes and multiattribute indexes based on P.
Step 3: deploy these indexes on Mapper and Reducer
Step 4: for every incoming tuple t ← stream S
while t! = empty do
 (1)Search in the interval index in Mapper;
 (2)Merge all results from Mapper and output satisfied queries;
P = LCN −;//search v in LCN-Index;
