[jira] [Created] (IGNITE-17835) partition lost check improvement
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.
