Hi [~slava.koptilin] ,
yes, the idea is that ignite would pull data from the remote storage on demand
(first use), and start managing it from that point onwards within the service
context, pushing it back for sharing (across services) and backup purposes. the
config:
{code:java}
val cfg = new CacheConfiguration[String, BinaryObject](s"name")
cfg.setBackups(1)
cfg.setCacheMode(CacheMode.PARTITIONED)
cfg.setAtomicityMode(CacheAtomicityMode.ATOMIC)
cfg.setGroupName(s"name")
cfg.setDataRegionName("name")
cfg.setReadThrough(true)
cfg.setCacheLoaderFactory(new CachedEntityStorage.CacheLoaderFactory(...))
cfg.setWriteThrough(true)
cfg.setCacheWriterFactory(new CachedEntityStorage.CacheWriterFactory(...))
cfg.setWriteBehindEnabled(true)
cfg.setWriteBehindCoalescing(true)
cfg.setWriteBehindFlushSize(0)
cfg.setWriteBehindFlushFrequency(1000)
cfg.setWriteBehindFlushThreadCount(2)
cfg.setWriteBehindBatchSize(32)
cfg.setStoreKeepBinary(true)
{code}
the region is configured with persistence=true on all ignite server nodes
Thanks for looking into this!
