Example 1 with LongListOffHeap

use of com.swirlds.jasperdb.collections.LongListOffHeap in project hedera-services by hashgraph.

the class IndexDumpBench method setup.

@Setup(Level.Trial)
public void setup() throws Exception {
    // crate a pile of data in RAM
    final long GB = 1024 * 1024 * 1024;
    final long sizeBytes = dataSizeGb * GB;
    final long sizeLongs = sizeBytes / Long.BYTES;
    System.out.println("sizeBytes = " + sizeBytes);
    System.out.println("sizeLongs = " + sizeLongs);
    Random random = new Random(1234);
    data = memoryType.equals("heap") ? new LongListHeap() : new LongListOffHeap();
    for (long i = 0; i < sizeLongs; i++) {
        data.put(i, random.nextLong());
    }
}
