Maxim Muzafarov updated IGNITE-11729: ------------------------------------- Fix Version/s: (was: 2.8) 2.9 > Low description for lost policy functional > ------------------------------------------ > > Key: IGNITE-11729 > URL: https://issues.apache.org/jira/browse/IGNITE-11729 > Project: Ignite > Issue Type: Improvement > Components: documentation > Affects Versions: 2.7 > Reporter: ARomantsov > Priority: Major > Fix For: 2.9 > > > Current description in > https://apacheignite.readme.io/docs/partition-loss-policies seems not covered > persistence case and text description is not clear > Probably we need to transform it into two tables (in-memory, persistence) > Rows - cache_write, cache_read, cache_remove,sql_read, sql_write > Columns - READ_ONLY_SAFE ,READ_ONLY_ALL, READ_WRITE_SAFE, etc > {code:java} > Policies > Ignite supports the following PartitionLossPolicies: > READ_ONLY_SAFE - all writes to a cache/table will fail with an exception. > Reads will only be allowed for entries belonging to survived/alive > partitions. Reads from lost partitions will fail with an exception. > READ_ONLY_ALL - reads are allowed from any partition including the lost ones. > An exception is thrown in an attempt to write to any partition. The result of > reading from a lost partition is undefined and may be different on different > nodes in the cluster. > READ_WRITE_SAFE - all reads and writes are allowed for entries in > survived/alive partitions. All reads and writes of entries belonging to the > lost partitions will fail with an exception. > READ_WRITE_ALL - all reads and writes will proceed as if all partitions were > in a consistent state (as if no partition loss happened). The result of > reading from a lost partition is undefined and may be different on different > nodes in the cluster. > IGNORE - this mode never marks a lost partition as lost, pretending that no > partition loss has happened and clearing the partition loss state right away. > Technically, the partition will not be added to the collection of > lostPartitions which is the main difference from READ_WRITE_ALL mode. IGNORE > mode is used by default. > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
