Hi! I made the observation that loading data initially into the ignite-cluster with native persistence enabled is usually a lot faster than subsequent loadings of the same data, that is 30 min (initially) vs 52 min (4th time) for 170 GB of data.
Does this indicate bad configurations from our side or is this expected behaviour? In fact we are quite happy with the initial loading speed of our data but will generally need to overwrite significant parts of it (which is the reasons for my question). I already tried to apply all the suggestion mentioned in https://apacheignite.readme.io/docs/durable-memory-tuning. We are using ignite 2.8.1 currently. Here is our data storage configuration: <property name="\"dataStorageConfiguration\""> <bean class="\"org.apache.ignite.configuration.DataStorageConfiguration\""> <property name="\"walMode\"" value="\"BACKGROUND\""/> <property name="\"writeThrottlingEnabled\"" value="\"true\""/> <property name="\"pageSize\"" value="\"#{4 * 1024}\""/> <property name="\"walSegmentSize\"" value="\"#{2 * 1000 * 1000 * 1000}\""/> <property name="\"maxWalArchiveSize\"" value="\"#{10L * 1024 * 1024 * 1024}\""/> <property name="\"defaultDataRegionConfiguration\""> <bean class="\"org.apache.ignite.configuration.DataRegionConfiguration\""> <property name="\"persistenceEnabled\"" value="\"true\""/> <property name="\"checkpointPageBufferSize\"" value="\"#{2L * 1024 * 1024 * 1024}\""/> <property name="\"name\"" value="\"Default_Region\""/> <property name="\"initialSize\"" value="\"${IGNITE_DEFAULT_REGION}\""/> <property name="\"maxSize\"" value="\"${IGNITE_DEFAULT_REGION}\""/> </bean> </property> <property name="\"storagePath\"" value="\"/persistence\""/> <property name="\"walPath\"" value="\"/wal\""/> <property name="\"walArchivePath\"" value="\"/wal\""/> </bean> Thanks in advance! -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
