Insertion speed is slower because writeBehindEnbled is true

I am using the Ignite Cache adapter, setting the entry as true.

Scenario 1:

  • When I write, I save the data to HBase.
  • For this, I inserted 100,000 objects into Ignite and then into HBase, the time it took to do this was about 82 seconds.

Scenario 2:

  • I made the write-behind property true.
  • I inserted 100,000 objects into Ignite and then into HBase, the time it took to do this was about 124 seconds.

Below are the results.

    Write-behind      Objects      Time in ms

     true             1,00,000      81962
     false            1,00,000      123517

As far as I know, if we use write cache it works as asynchronous mode But it gives unexpected result. I am something wrong.

What result do you expect here? The "Write-behind" mode simply schedules the store update later, which is much faster than updating immediately with every cache change.



To customize its behavior, you can check setWriteBehindBatchSize , setWriteBehindFlushFrequency , setWriteBehindFlushSize , setWriteBehindFlushThreadCount .
