-------------------------------------
Summary: Need to revisit compute grid checkpoints
Key: IGNITE-4265
URL: https://issues.apache.org/jira/browse/IGNITE-4265
Project: Ignite
Issue Type: Task
Reporter: Yakov Zhdanov
Priority: Minor
I. Shared fs checkpoint SPI seems to be totally wrong
Problems spotted in code
# Blocking IO API
# No locks or synchronization
Please see GridSharedFsCheckpointSpiMultiThreadedSelfTest
I would think of removing shared FS checkpoints and move to distributed cache.
II. Having the above I would do:
# Revisit checkpoints SPI/manager. I would probably replace it with checkoints
processor using distributed cache(s)
# distributed caches can be configured in configuration or on the fly using
templates. This needs to be elaborated further.
#
org.apache.ignite.internal.managers.checkpoint.GridCheckpointManager#onSessionEnd
seems to be handy for clean up and can be implemented with cache queries -
session ID should be added to each entry
