Research prototype for stream join algorithms

This repo contains:

hu.bme.vzqixx.punctuations Java package to experiment with punctuated streams
- InsertPunctuation insert punctuation to a stream represented in a file
  Usage: InsertPunctuation punctuationMode punctuationOnFieldPosition path inputFile outputFile, where punctuationMode can be: NONE, TAIL, HEAD_AND_TAIL
- PunctuatedIndexJoin implement a punctuation-aware left outer join between a stream and a persistent relation
  Usage: PunctuatedIndexJoin punctuationMode punctuationOnFieldPositionInS punctuationOnFieldPositionInR path streamingRelation persistentRelation, where punctuationMode can be: NONE, TAIL, HEAD_AND_TAIL

Compilation

Pending to add build tool. Until then, use the following commands under bash 4 from the git root:

mkdir -p out && shopt -s globstar && javac -d out/ src/**/*.java
