Examples with GlobalMemoryManager org.apache.phoenix.memory.GlobalMemoryManager used on opensource projects

Example 1 with GlobalMemoryManager

use of org.apache.phoenix.memory.GlobalMemoryManager in project phoenix by apache.

the class TenantCacheTest method testInvalidateClosesMemoryChunk.

@Test
public void testInvalidateClosesMemoryChunk() throws SQLException {
    int maxServerCacheTimeToLive = 10000;
    long maxBytes = 1000;
    int maxWaitMs = 1000;
    GlobalMemoryManager memoryManager = new GlobalMemoryManager(maxBytes, maxWaitMs);
    TenantCacheImpl newTenantCache = new TenantCacheImpl(memoryManager, maxServerCacheTimeToLive);
    ImmutableBytesPtr cacheId = new ImmutableBytesPtr(Bytes.toBytes("a"));
    ImmutableBytesWritable cachePtr = new ImmutableBytesWritable(Bytes.toBytes("a"));
    newTenantCache.addServerCache(cacheId, cachePtr, ByteUtil.EMPTY_BYTE_ARRAY, cacheFactory, true);
    assertEquals(maxBytes - 1, memoryManager.getAvailableMemory());
    newTenantCache.removeServerCache(cacheId);
    assertEquals(maxBytes, memoryManager.getAvailableMemory());
}

Example 2 with GlobalMemoryManager

use of org.apache.phoenix.memory.GlobalMemoryManager in project phoenix by apache.
