如何从Spark ignite RDD启用对永久存储的直写

Question

JavaIgniteRDD is not storing the data in persistent storage MySQL.

I have configured 2 caches with MySQL as persistent storage. One is updated from regular Ignite cache, other is updated though JavaIgniteRDD.savePairs.

In both the cases data is being updated in Ignite Cache.

But JavaIgniteRDD.savePairs is not persisting the data to MySQl. In-fact CacheStore write method itself not invoked.

Is this an expected behaviour?

尝试使用overwrite=true调用savePairs ：

igniteRdd.savePairs(rdd, true)
