----------------------------------------
Summary: Consider using RandomAccessFileIoFactory instead of
AsyncFileIoFactory
Key: IGNITE-26724
URL: https://issues.apache.org/jira/browse/IGNITE-26724
Project: Ignite
Issue Type: Improvement
Reporter: Kirill Tkalenko
Assignee: Kirill Tkalenko
While investigating checkpoint slowdowns in aipersist, I tried replacing
*org.apache.ignite.internal.fileio.AsyncFileIoFactory* with
*org.apache.ignite.internal.fileio.RandomAccessFileIoFactory* and noticed a
performance boost for writing dirty pages and fsync files, but for a small
number of files and pages. We need to investigate this in more detail and try
it with a larger number of pages.
It's also worth noting that *AsyncFileIoFactory* was introduced in AI 2.0 for a
reason, but to address the issue of thread interrupts that were causing
*FileChannel* to close. We need to check if this is the issue here. If the
problem persists, we can consider using *RandomAccessFileIoFactory* for page
writes to speed them up.
