Vladimir Steshin updated IGNITE-20138:
--------------------------------------
Description:
We create PageMemoryImpl as:
{code:java}
PageMemoryImpl pageMem = new PageMemoryImpl(
wrapMetricsPersistentMemoryProvider(memProvider, regMetrics),
calculateFragmentSizes(
regCfg.getName(),
dsCfg.getConcurrencyLevel(),
cacheSize,
chpBufSize
),
cctx,
pageMgr,
dsCfg.getPageSize(),
(fullId, pageBuf, tag) -> {
regMetrics.onPageWritten();
// Write page to disk.
pageMgr.write(fullId.groupId(), fullId.pageId(), pageBuf, tag,
true);
getCheckpointer().currentProgress().updateEvictedPages(1);
},
trackable,
this,
regMetrics,
regCfg,
resolveThrottlingPolicy(),
() -> getCheckpointer().currentProgress()
);
{code}
Where `getCheckpointer()` and the `CheckpointLockStateChecker stateChecker`
constructor parameter can be not bound to PageMemory's data region. For
instance, defragmentation uses own region and own lightweight checkpointer. See
IGNITE-19904
