Alexey Goncharuk commented on IGNITE-5479:
------------------------------------------
This does not work: we need Long to distinguish between the following two cases:
{code}
new PersistentStoreConfiguration(); // Ignite will automatically adjust
checkpoint buffer size
{code}
and
{code}
new PersistentStoreConfiguration().setCheckpointPageBufferSize(someValue);
// Ignite will NOT adjust the checkpoint buffer size even if someValue ==
DEFAULT_VALUE
{code}
This can be solved by adding a flag isDefaultPageBufferSize on
PersistentStoreConfiguration, but the approach with Long looks more clear to
me. What do you think?

>
> Improve {{PersistentStoreConfiguration}} to be consistent with other
> configuration classes:
> * {{LockWaitTime}} - should be {{long}} and in milliseconds
> * {{getCheckpointingPageBufferSize}} should return {{long}} instead of
> {{Long}}
> * {{WalFlushFrequency}} - should be {{long}} and in milliseconds
> * {{WalFsyncDelay}} - should be {{long}} and in milliseconds. Add javadoc.
