Alexey Stelmak reassigned IGNITE-9903: -------------------------------------- Assignee: Alexey Stelmak (was: Andrey Gura) > Copy only actual amount of data during archiving of WAL segment > --------------------------------------------------------------- > > Key: IGNITE-9903 > URL: https://issues.apache.org/jira/browse/IGNITE-9903 > Project: Ignite > Issue Type: Improvement > Reporter: Andrey Gura > Assignee: Alexey Stelmak > Priority: Major > Fix For: 2.8 > > > Current WAL archiver implementation copies full WAL segment to the archive > while actual size of the segment can be significantly less then > {{maxWalSegmentSize}} (segment files are preallocated for max possible > segment size). > In order to reduce disk space consuming we need copy only actual data of > segment using {{SWITCH_SEGMENT_RECORD}} as marker. It will require some kind > of WAL iterator implementation that will just copy WAL records using > information about record size without records deserialization. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
