Examples with ReuseList org.apache.ignite.internal.processors.cache.persistence.tree.reuse.ReuseList used on opensource projects

Example 1 with ReuseList

use of org.apache.ignite.internal.processors.cache.persistence.tree.reuse.ReuseList in project ignite by apache.

the class IgniteCacheOffheapManagerImpl method allocateForTree.

/**
 * @return Page ID.
 * @throws IgniteCheckedException If failed.
 */
private long allocateForTree() throws IgniteCheckedException {
    ReuseList reuseList = grp.reuseList();
    long pageId;

        pageId = grp.dataRegion().pageMemory().allocatePage(grp.groupId(), INDEX_PARTITION, FLAG_IDX);
    return pageId;
}

Example 2 with ReuseList

use of org.apache.ignite.internal.processors.cache.persistence.tree.reuse.ReuseList in project ignite by apache.

 * @param cacheType Cache type.
 * @param affNode Affinity node flag.
 * @param cacheObjCtx Cache object context.
 * @param exchTopVer Current topology version.
