the class RowStoreTest method randomRowInfos.

private void randomRowInfos(long seed) throws Exception {

    final Map<Integer, RowInfo> rowInfos = new HashMap<>();
    for (int i = 0; i < 200; i++) {
        RowInfo rowInfo = randomRowInfo("Test", keyColumns, withAltKey, withIndex, rnd);
        Integer version = rs.schemaVersion(rowInfo, true, ix.id(), false);
        RowInfo existing = rowInfos.get(version);
        if (existing == null) {
            rowInfos.put(version, rowInfo);
        } else {
