Jedis 4 Breaking Changes

• The BinaryJedis and BinaryJedisCluster classes have been removed.

  The methods from these classes are available in the Jedis and JedisCluster classes respectively.

• The following cases now throws an IllegalStateException instead of a JedisDataException.

  • Cannot use Jedis when in Multi. Please use Transaction or reset Jedis state.
  • Cannot use Jedis when in Pipeline. Please use Pipeline or reset Jedis state.

• The Redis transaction methods multi(), exec() and discard() have been removed from Pipeline.

• The execGetResponse() method has been removed from Transaction.

• The watch() and unwatch() methods from the Transaction class are unsupported within MULTI (i.e., after the multi() method). However, watch() and unwatch () can still be used before calling MULTI.

• The JedisCluster constructors with GenericObjectPoolConfig<Jedis> now accept GenericObjectPoolConfig<Connection>.

• All JedisCluster constructors now throw a JedisClusterOperationException if unable to connect to any of the provided HostAndPort(s). Previously, the connection would go into an unusable state.

• JedisCluster.getClusterNodes() returns Map<String, ConnectionPool> instead of Map<String, JedisPool>.

• JedisCluster.getConnectionFromSlot(int) returns Connection instead of Jedis.

• JedisNoReachableClusterNodeException has been removed. JedisClusterOperationException, with a similar message, is thrown instead.

• JedisClusterMaxAttemptsException has been removed. JedisClusterOperationException, with a similar message, is thrown instead.

• JedisExhaustedPoolException has been removed. A JedisException with a similar message is thrown instead.

• Many sorted set methods return a Java List instead of a Set. See the complete list.

• Many methods return primitive values) (long/boolean/double instead of Long/Boolean/ Double). See the complete list.

• scriptExists(byte[]) method now returns Boolean instead of Long.

• scriptExists(byte[]...) method now returns List<Boolean> instead of List<Long>.

• In the xadd method with StreamEntryID parameter, sending untyped null raises an exception.

  Casting the null to StreamEntryID ((StreamEntryID) null) resolves this issue.

• In the xrange and xrevrange methods with StreamEntryID parameters, sending untyped nulls for both start and end parameters raises an exception.

  Casting the nulls to StreamEntryID ((StreamEntryID) null) resolves this issue.

• The return type of Jedis.shutdown() is now void. Previously, it would return null.

• The eval and evalsha methods are now non-blocking. These methods were blocking in Jedis 3.x.

• The HostAndPort.localhost constant has been removed.

• The following methods have been removed from HostAndPort class:

  • extractParts()
  • parseString()
  • convertHost()
  • setLocalhost()
  • getLocalhost()
  • getLocalHostQuietly()

• The following classes have been moved to the redis.clients.jedis.args package.

  • BitOP
  • GeoUnit
  • ListPosition

• The following classes have been moved to the redis.clients.jedis.params package.

  • BitPosParams
  • ScanParams
  • SortingParams
  • ZParams

• The following classes have been moved to the redis.clients.jedis.resps package.

  • AccessControlLogEntry
  • AccessControlUser
  • GeoRadiusResponse
  • ScanResult
  • Slowlog
  • StreamConsumersInfo
  • StreamEntry
  • StreamGroupInfo
  • StreamInfo
  • StreamPendingEntry
  • StreamPendingSummary
  • Tuple

• Jedis and JedisPool constructors with a String parameter, and no int parameter, only support a URL or URI string.

  • Jedis(String)
  • JedisPool(String)
  • JedisPool(String, SSLSocketFactory, SSLParameters, HostnameVerifier)
  • JedisPool(GenericObjectPoolConfig<Jedis>, String)

• The Client and BinaryClient classes have been removed.

• redis.clients.jedis.commands package has been reimplemented, meaning that the Commands interfaces have been restructured.

• The ShardedJedisPool, Sharded, ShardedJedis, BinaryShardedJedis, ShardInfo, JedisShardInfo classes have been removed.

  • Introduced JedisSharding class to replace ShardedJedisPool.

    Earlier code without the use of "name" and "weight" (in ShardInfo/JedisShardInfo) are transferable to the new class.

• ShardedJedisPipeline class has been removed.

  • Introduced ShardedPipeline class to replace ShardedJedisPipeline.

• The type of Protocol.CHARSET has been changed to java.nio.charset.Charset.

• Jedis.debug(DebugParams) method has been removed.

• The DebugParams class has been removed.

• The Jedis.sync() method has been removed.

• The Jedis.pubsubNumSub(String...) method now returns Map<String, Long> instead of Map<String, String>.

• setDataSource method in Jedis class now has protected access.

• JedisPoolAbstract class has been removed. Use Pool<Jedis>.

• The Pool.initPool() method has been removed.

• The Pool.getNumActive() method now returns 0 (via GenericObjectPool) when the pool is closed.

• The Connection.getRawObjectMultiBulkReply() method has been removed. Use Connection.getUnflushedObjectMultiBulkReply() method.

• The Queable.getResponse(Builder<T> builder) method has been renamed to Queable.enqueResponse(Builder<T> builder).

• All methods in Queable are now final:

  • clean()
  • generateResponse(Object data)
  • enqueResponse(Builder<T> builder)
  • getPipelinedResponseLength()

• These BuilderFactory implementations have been removed:

  • OBJECT (use RAW_OBJECT)
  • BYTE_ARRAY_ZSET (use BINARY_LIST or BINARY_SET)
  • BYTE_ARRAY_MAP (use BINARY_MAP)
  • STRING_ZSET (use STRING_LIST or STRING_SET)
  • EVAL_RESULT (use ENCODED_OBJECT)
  • EVAL_BINARY_RESULT (use RAW_OBJECT)

• All String variables representing Cluster, Sentinel and PubSub subcommands in Protocol class have been removed.

• ClientKillParams.Type has been removed. Use ClientType.

• ClusterReset has been removed. Use ClusterResetType.

• The JedisClusterHostAndPortMap interface has been removed. Use the HostAndPortMapper interface.

• JedisClusterHashTagUtil class has been renamed to JedisClusterHashTag.

• The KeyMergeUtil class has been removed.
