Redis Is it possible that if a client crashes while writing objects to redis , then there will be partial values stored ?

Spring boot application with following redis template

RedisTemplate<String, String> template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new JdkSerializationRedisSerializer());
template.setHashValueSerializer(new JdkSerializationRedisSerializer());

as per title, what happens if the app crashed while writing objects to redis ? for example a json payload thanks

A redis command is either execute or it's not, so either Redis will receive the full command and execute it, or the connection will be closed and Redis will drop the partial command.

Thanks for replying, isn't the serialiser writing in blocks of 1024 by default ? What if the object is big and the stream is closed I the middle while writing to redis store?

No matter how the client library serializes and sends the data, the command will be received by Redis and processed atomically. If you have questions for a particular client (Java?) better ask in that forum. This issue tracker is for the Redis database itself.
