Usage example

RedisBloom

Config config = new Config();
config.useSingleServer().setAddress("redis://127.0.0.1:6379");
RedisBloomClient redisBloomClient = new RedisBloomClient(config);

BloomFilter bloomFilter = redisBloomClient.getRBloomFilter("bf");
bloomFilter.create(0.1d, 100);
bloomFilter.madd(new String[] {"a", "b", "c"});

TopKFilter topKFilter = redisBloomClient.getTopKFilter("topk_add");
topKFilter.reserve(1, 2000, 7, 0.925d);
topKFilter.add("test");
List<Boolean> itemExits = topKFilter.query("test");
Map<String, Integer> itemIncrement = new HashMap<>();
itemIncrement.put("test", 3);
topKFilter.incrby(itemIncrement);
List<String> allItems = topKFilter.list();

CountMinSketch countMinSketch = redisBloomClient.getCountMinSketch("cms_add");
countMinSketch.create(10, 10);
CountMinSketchInfo countMinSketchInfo = countMinSketch.getInfo();

CuckooFilter cuckooFilter = redisBloomClient.getCuckooFilter("cf_insert");
List<Boolean> result = cuckooFilter.insert(-1L, false, "a");

redisBloomClient.shutdown();

RediSearch

Config config = new Config();
config.useSingleServer().setAddress("redis://" + DEFAULT_HOST + ":" + DEFAULT_PORT);
RediSearchClient rediSearchClient = new RediSearchClient(config);

RediSearch rediSearch = rediSearchClient.getRediSearch("testSearch");
rediSearch.createIndex(new Schema()
    .addField(new TextField("title"))
    .addField(new TextField("content"))
    .addField(new Field("age", FieldType.NUMERIC))
    .addField(new Field("location", FieldType.GEO)));

Map<String, Object> fields = new HashMap<>();
fields.put("title", "Hi");
fields.put("content", "OOOO");
rediSearch.addDocument(new Document(String.format("doc1"), 1.0d, fields), new DocumentOptions());

// Search with NumericFilter
SearchResult searchResult = rediSearch.search("number", new SearchOptions()
                .noStopwords()
                .language(RSLanguage.ENGLISH)
                .filter(new NumericFilter("age", 1, 4)));

// Search with GeoFilter
searchResult = rediSearch.search("number", new SearchOptions()
                .noStopwords()
                .language(RSLanguage.ENGLISH)
                .filter(new GeoFilter("location", 15, 37, 200, GeoFilter.Unit.KILOMETERS)));

RedisTimeSeries

Config config = new Config();
config.useSingleServer().setAddress("redis://192.168.50.16:6383");
RedisTimeSeriesClient redisTimeSeriesClient = new RedisTimeSeriesClient(config);

RedisTimeSeries redisTimeSeries = redisTimeSeriesClient.getRedisTimeSeries();
long timestamp = System.currentTimeMillis();
redisTimeSeries.add(new Sample("temperature:2:32", Sample.Value.of(timestamp, 26)), new TimeSeriesOptions()
                .retentionTime(6000L)
                .unCompressed()
                .labels(new Label("sensor_id", "2"), new Label("area_id", "32")));
redisTimeSeriesClient.shutdown();

RedisAI

Config config = new Config();
config.useSingleServer().setAddress("redis://127.0.0.1:6379");
RedisAIClient redisAIClient = new RedisAIClient(config);

RedisAI redisAI = redisAIClient.getRedisAI();
redisAI.setTensor("tensor1", DataType.FLOAT, new int[]{2, 2}, null, new String[]{"1", "2", "3", "4"});
redisAIClient.shutdown();

RedisGears

Config config = new Config();
config.useSingleServer().setAddress("redis://127.0.0.1:6379");
RedisGearsClient redisGearsClient = new RedisGearsClient(config);

RedisGears redisGears = redisGearsClient.getRedisGears();
redisGears.pyExecute("GB().run()", false);
redisGearsClient.shutdown();

RedisJSON

Config config = new Config();
config.useSingleServer().setAddress("redis://127.0.0.1:6379");
RedisJSONClient redisJSONClient = new RedisJSONClient(config);

RedisJSON redisJSON = redisJSONClient.getRedisJSON();
String key = "foo";
Map<String, Object> m = new HashMap<>();
m.put("id", 1);
m.put("name", "lisi");
redisJSON.set(key, SetArgs.Builder.create(".", GsonUtils.toJson(m)));
Map<String, Object> actual = redisJSON.get(key, Map.class, new GetArgs().path(".").indent("\t").newLine("\n").space(" "));
redisJSONClient.shutdown();
