Examples with CacheDataRowStore org.apache.ignite.internal.processors.cache.tree.CacheDataRowStore used on opensource projects

Example 1 with CacheDataRowStore

use of org.apache.ignite.internal.processors.cache.tree.CacheDataRowStore in project ignite by apache.

the class IgniteCacheOffheapManagerImpl method createCacheDataStore0.

/**
 * @param p Partition.
 * @return Cache data store.
 * @throws IgniteCheckedException If failed.
 */
protected CacheDataStore createCacheDataStore0(int p) throws IgniteCheckedException {
    long rootPage = allocateForTree();
    CacheDataRowStore rowStore = new CacheDataRowStore(grp, grp.freeList(), p);
    String dataTreeName = grp.cacheOrGroupName() + "-" + treeName(p);
    CacheDataTree dataTree = new CacheDataTree(grp, dataTreeName, grp.reuseList(), rowStore, rootPage, true, ctx.diagnostic().pageLockTracker(), FLAG_IDX);
    return new CacheDataStoreImpl(p, rowStore, dataTree, () -> pendingEntries, grp, busyLock, log, null);
}
