Examples with LongStreamV2Checkpoint io.prestosql.orc.checkpoint.LongStreamV2Checkpoint used on opensource projects

Example 1 with LongStreamV2Checkpoint

use of io.prestosql.orc.checkpoint.LongStreamV2Checkpoint in project hetu-core by openlookeng.

the class LongInputStreamV2 method seekToCheckpoint.

@Override
public void seekToCheckpoint(LongStreamCheckpoint checkpoint) throws IOException {
    LongStreamV2Checkpoint v2Checkpoint = (LongStreamV2Checkpoint) checkpoint;
    // if the checkpoint is within the current buffer, just adjust the pointer
    if (lastReadInputCheckpoint == v2Checkpoint.getInputStreamCheckpoint() && v2Checkpoint.getOffset() <= numLiterals) {
        used = v2Checkpoint.getOffset();
    } else {
        // otherwise, discard the buffer and start over
        input.seekToCheckpoint(v2Checkpoint.getInputStreamCheckpoint());
        numLiterals = 0;
        used = 0;
        skip(v2Checkpoint.getOffset());
    }
}

Example 2 with LongStreamV2Checkpoint

use of io.prestosql.orc.checkpoint.LongStreamV2Checkpoint in project hetu-core by openlookeng.

the class LongOutputStreamV2 method recordCheckpoint.

@Override
public void recordCheckpoint() {
    checkState(!closed);
    checkpoints.add(new LongStreamV2Checkpoint(numLiterals, buffer.getCheckpoint()));
