Field Details

MULTI_THREAD_FILE_SIZE

public static final Option<Long> MULTI_THREAD_FILE_SIZE

Size of the file over which we would use multi-threaded parsing. Multiple files are parsed in multiple threads but unless the input file size is greater this limit a single parsing thread will be used for that file. Set to -1 to use multi-threaded parsing for every file and input stream for which there is no size information. Multi-threaded parsing is currently limited to NTriples and NQuads formats.

THREAD_COUNT

public static final Option<Integer> THREAD_COUNT

The number of threads to use for parsing a single file in multiple threads.

BATCH_SIZE

public static final Option<Integer> BATCH_SIZE

The number of input lines that will be passed to parsing threads as a batch.

QUEUE_SIZE

public static final Option<Integer> QUEUE_SIZE

The maximum number of batches that will be kept in memory when multiple threads are being used to parse a single file. Setting this value higher will cause more memory to be used.
