YuJue Li created IGNITE-17835:
---------------------------------

             Summary: partition lost check improvement
                 Key: IGNITE-17835
                 URL: https://issues.apache.org/jira/browse/IGNITE-17835
             Project: Ignite
          Issue Type: Improvement
          Components: cache
    Affects Versions: 2.13
            Reporter: YuJue Li
             Fix For: 2.15


Start two nodes with native persistent enabled, and then activate it.

create a table with no backups, sql like follows:

CREATE TABLE City (
  ID INT,
  Name VARCHAR,
  CountryCode CHAR(3),
  District VARCHAR,
  Population INT,
  PRIMARY KEY (ID, CountryCode)
) WITH "template=partitioned, affinityKey=CountryCode, CACHE_NAME=City, KEY_TYPE=demo.model.CityKey, VALUE_TYPE=demo.model.City";

INSERT INTO City(ID, Name, CountryCode, District, Population) VALUES (1,'Kabul','AFG','Kabol',1780000);
INSERT INTO City(ID, Name, CountryCode, District, Population) VALUES (2,'Qandahar','AFG','Qandahar',237500);

then execute SELECT COUNT(*) FROM city; 


normal.

then kill one node.

then execute SELECT COUNT(*) FROM city; 


Failed to execute query because cache partition has been lostPart [cacheName=City, part=0]

this alse normal.

Next, start the node that was shut down before.

then execute SELECT COUNT(*) FROM city; 


Failed to execute query because cache partition has been lostPart [cacheName=City, part=0]

At this time, all partitions have been recovered, and all baseline nodes are ONLINE. Execute reset_lost_partitions operation at this time seems redundant.
