The method is named "lookupRecord".
"lookupRecord" seems to find a related record.
But the method is checking whether recordsSnapshot contains the id or not.
Thus, the method name "containsRecord" is more intuitive than "lookupRecord".
Travis CI has been reporting test failures.
Looking on logs I could see a critical failure happening but not much information on why.
This will help identify further issues.
Adding new metrics for tracking message counts and sizes on a Queue.
This includes tracking metrics for pending, delivering and scheduled
messages. The paging store also tracks message size now.
When live start replication, it must make sure there is
no pending write in message & bindings journal, or we may
lost journal records during initial replication.
So we need flush append executor after acquire StorageManager's
write lock, before Journal's write lock.
Also we set a 10 seconds timeout when flush, the same as
Journal::flushExecutor. If we failed to flush in 10 seconds,
we abort replication, backup will try again later.
Use OrderedExecutorFactory::flushExecutor to flush executor
The MappedSequentialFile relies on the assumption that any writers
won't exceed the maximum capacity of the file, leaving the JVM to crash otherwise.
This commit adds proper bounds checking on write operations (and position changes too)
in order to provide recoverable effects if such scenario should occour.
In addition are provided minor fixes on Mapped and Nio SequentialFile::fill behaviour
to match the original contract.
- it is now possible to disable the TimedBuffer
- this is increasing the default on libaio maxAIO to 4k
- The Auto Tuning on the journal will use asynchronous writes to simulate what would happen on faster disks
- If you set datasync=false on the CLI, the system will suggest mapped and disable the buffer timeout
This closes#1436
This commit superseeds #1436 since it's now disabling the timed buffer through the CLI
Instead of wait to flush an executor,
I have added a method isFlushed() which will just translate to the
state on the OrderedExecutor.
In the case another executor is provided (for tests) there's a delegate
into normal executors.
