########## File path: pinot-tools/src/main/java/org/apache/pinot/tools/data/generator/StringGenerator.java ########## @@ -56,11 +65,18 @@ public void init() { @Override public Object next() { + if (numberOfValuesPerEntry == 1) { + return getNextString(); + } + return MultiValueGeneratorHelper.generateMultiValueEntries(numberOfValuesPerEntry, rand, this::getNextString); + } + + private String getNextString() { return vals.get(rand.nextInt(cardinality)); Review comment: Vals is a hashmap. This is where we are going to run into issues with generation based approach where the characteristics file specifies a very high cardinality for column(s). The HashMap will likely hit OOM. So the other approach of estimating the memory without the completed segment all together becomes quite essential. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
