Maxim Muzafarov updated IGNITE-11156: ------------------------------------- Fix Version/s: (was: 2.8) > FreeLists are overflowed with pages with almost no free space left > ------------------------------------------------------------------ > > Key: IGNITE-11156 > URL: https://issues.apache.org/jira/browse/IGNITE-11156 > Project: Ignite > Issue Type: Improvement > Reporter: Ivan Rakov > Assignee: Ivan Rakov > Priority: Major > Time Spent: 20m > Remaining Estimate: 0h > > {code:java} > /** */ > private static final int MIN_PAGE_FREE_SPACE = 8; > {code} > If data page has 8 unused bytes or more, it will be stored in a free list. As > result, free lists mostly contain "free pages" that are actually useless: > pair of (boolean, boolean) takes approximately 50 bytes. I think, we'll > increase this constant to something like 40, memory will be used more > efficiently and WAL usage will decrease in result. -- This message was sent by Atlassian Jira (v8.3.4#803005)
