Write lists for many keys to Redis

[frederic-schmaljohann]

I would like to write lists values for multiple keys with spark-redis.

The data structure I would like to write is basically key:String, value:List[String].

Using regular redis commands I would use LPUSH for example.

So far I have only found sc.toRedisLIST which doesn't seem to support multiple keys.

Am I missing something?

Thanks in advance

Hi @frederic-schmaljohann ,
The API your are looking for is missing, but shouldn't be a problem to add that. I will try to implement it on the weekend.

Thanks for implementing this @fe2s . When do you think the change will be released?

Hi @frederic-schmaljohann ,
The PR #216 was to address issue #205 which is similar to your request, but we needed byte oriented API. Actually you can use toRedisByteLIST from that PR if you convert strings to byte arrays before saving. However I still want to have a similar function, but the one that works with strings. I will let you know once it's ready.

Added toRedisLISTs API
Will be released in 2.4.2
