    HashIndexDefinitionBuilder builder = SchemaBuilders.hashIndex("testHI").withColumns("A", "B", "C").withHints(Collections.singletonMap("param", "value"));
    HashIndexDefinition idx = builder.build();
    getTbl().change(ch -> SchemaConfigurationConverter.addIndex(idx, ch)).get();
    TableDefinition tbl = SchemaConfigurationConverter.convert(getTbl().value());
    HashIndexDefinition idx2 = (HashIndexDefinition) getIdx(idx.name(), tbl.indices());
