Examples with NativePool org.apache.cassandra.utils.memory.NativePool used on opensource projects

Example 1 with NativePool

use of org.apache.cassandra.utils.memory.NativePool in project cassandra by apache.

the class Memtable method createMemtableAllocatorPool.

private static MemtablePool createMemtableAllocatorPool() {
    long heapLimit = DatabaseDescriptor.getMemtableHeapSpaceInMiB() << 20;
    long offHeapLimit = DatabaseDescriptor.getMemtableOffheapSpaceInMiB() << 20;
    final float cleaningThreshold = DatabaseDescriptor.getMemtableCleanupThreshold();
    final MemtableCleaner cleaner = ColumnFamilyStore::flushLargestMemtable;
    switch(DatabaseDescriptor.getMemtableAllocationType()) {
        case unslabbed_heap_buffers_logged:
            return new HeapPool.Logged(heapLimit, cleaningThreshold, cleaner);
        case unslabbed_heap_buffers:
            return new HeapPool(heapLimit, cleaningThreshold, cleaner);
        case heap_buffers:
            return new SlabPool(heapLimit, 0, cleaningThreshold, cleaner);
        case offheap_buffers:
            return new SlabPool(heapLimit, offHeapLimit, cleaningThreshold, cleaner);
        case offheap_objects:
            return new NativePool(heapLimit, offHeapLimit, cleaningThreshold, cleaner);
        default:
            throw new AssertionError();
    }
}

Example 2 with NativePool

use of org.apache.cassandra.utils.memory.NativePool in project cassandra by apache.

the class CellSpecTest method data.

@Parameterized.Parameters(name = "{0}")
public static Collection<Object[]> data() {
    TableMetadata table = TableMetadata.builder("testing", "testing").addPartitionKeyColumn("pk", BytesType.instance).build();
    byte[] rawBytes = { 0, 1, 2, 3, 4, 5, 6 };
    ByteBuffer bbBytes = ByteBuffer.wrap(rawBytes);
    NativePool pool = new NativePool(1024, 1024, 1, () -> ImmediateFuture.success(true));
    NativeAllocator allocator = pool.newAllocator(null);
    OpOrder order = new OpOrder();
    List<Cell<?>> tests = new ArrayList<>();
    BiConsumer<ColumnMetadata, CellPath> fn = (column, path) -> {
        tests.add(new ArrayCell(column, 1234, 1, 1, rawBytes, path));
        tests.add(new BufferCell(column, 1234, 1, 1, bbBytes, path));
        tests.add(new NativeCell(allocator, order.getCurrent(), column, 1234, 1, 1, bbBytes, path));
    };
    // simple
    fn.accept(ColumnMetadata.regularColumn(table, bytes("simple"), BytesType.instance), null);
    // complex
    // seems NativeCell does not allow CellPath.TOP, or CellPath.BOTTOM
    fn.accept(ColumnMetadata.regularColumn(table, bytes("complex"), ListType.getInstance(BytesType.instance, true)), CellPath.create(bytes(UUIDGen.getTimeUUID())));
    return tests.stream().map(a -> new Object[] { a.getClass().getSimpleName() + ":" + (a.path() == null ? "simple" : "complex"), a }).collect(Collectors.toList());
}

Example 3 with NativePool

use of org.apache.cassandra.utils.memory.NativePool in project cassandra by apache.

the class ClusteringHeapSizeTest method data.

@Parameterized.Parameters(name = "{0}")
public static Collection<Object[]> data() {
    byte[] rawBytes = { 0, 1, 2, 3, 4, 5, 6 };
    NativePool pool = new NativePool(1024, 1024, 1, () -> ImmediateFuture.success(true));
    OpOrder order = new OpOrder();
    ArrayClustering array = ArrayClustering.make(rawBytes);
    BufferClustering buffer = BufferClustering.make(ByteBuffer.wrap(rawBytes));
    return Arrays.asList(new Object[][] { { array }, { buffer }, { new NativeClustering(pool.newAllocator(null), order.getCurrent(), array) } });
