Example 16 with Threads

use of org.openjdk.jmh.annotations.Threads in project atlasdb by palantir.

the class StreamStoreBenchmarks method loadSmallStream.

@Warmup(time = 1, timeUnit = TimeUnit.SECONDS)
@Measurement(time = 5, timeUnit = TimeUnit.SECONDS)
public void loadSmallStream(StreamingTable table) throws IOException {
    long id = table.getSmallStreamId();
    TransactionManager transactionManager = table.getTransactionManager();
    StreamTestTableFactory tables = StreamTestTableFactory.of();
    ValueStreamStore store = ValueStreamStore.of(transactionManager, tables);
    try (InputStream inputStream = transactionManager.runTaskThrowOnConflict(txn -> store.loadStream(txn, id));
        InputStreamReader reader = new InputStreamReader(inputStream, StandardCharsets.UTF_8);
        BufferedReader bufferedReader = new BufferedReader(reader)) {
