連接具有大量條目的表將引發異常

Question

我正在使用Apache Ignite，並嘗試使用SqlFieldsQuery多個緩存。 如果其中一個緩存具有200萬條記錄，則會引發以下異常：

Exception in thread "main" javax.cache.CacheException: Failed to run map query remotely.
    at org.apache.ignite.internal.processors.query.h2.twostep.GridReduceQueryExecutor.query(GridReduceQueryExecutor.java:652)

我該如何解決？

您應該檢查ID為b72073a8-e58e-4998-9ae5-fc4abf05a800的節點的日志。 應該有一個導致失敗的異常。
