Currently I'm using Apache Ignite v2.8.1 to preload a cache from the RDBMS. There are two tables with each 27M rows. The index is defined on a single column of type String in 1st table and Integer in the 2nd table. Together the total size of the two tables is around 120GB.
The preloading process (triggered using loadCacheAsync() from within a Java app) takes about 45hrs. The cache is persistence enabled and a common EBS volume (SSD) is being used for both the WAL and other locations. I'm unable to figure out the bottleneck for increasing the speed. Apart from defining a separate path for WAL and the persistence, is there any other way to load the cache faster (with indexing enabled) ? Thanks, Srikanta
