Re: Initial data loading from database

Hello! loadCache usually will only affect local partitions. There are no guarantees that entries loaded from cache store are in sync. Entries touched via Ignite APIs should be in sync. loadCache will not overwrite existing data. Regards, -- Ilya Kasnacheev пн, 1 февр. 2021 г. в 07:29, eerick
