Method Detail

withIOManager

TableWrite withIOManager(IOManager ioManager)

With IOManager, this is needed if 'write-buffer-spillable' is set to true.

TableWrite withMemoryPool(MemorySegmentPool memoryPool)

With MemorySegmentPool for the current table write.

getPartition

BinaryRow getPartition(InternalRow row)

Calculate which partition row belongs to.

getBucket

int getBucket(InternalRow row)

Calculate which bucket row belongs to.

write

void write(InternalRow row)
    throws Exception

Write a row to the writer.

Throws:

Exception

write

void write(InternalRow row,
           int bucket)
    throws Exception

Write a row with bucket.

Throws:

Exception

writeBundle

void writeBundle(BinaryRow partition,
                 int bucket,
                 BundleRecords bundle)
          throws Exception

Write a bundle records directly, not per row.

Throws:

Exception

compact

void compact(BinaryRow partition,
             int bucket,
             boolean fullCompaction)
      throws Exception

Compact a bucket of a partition. By default, it will determine whether to perform the compaction according to the 'num-sorted-run.compaction-trigger' option. If fullCompaction is true, it will force a full compaction, which is expensive.

NOTE: In Java API, full compaction is not automatically executed. If you set 'changelog-producer' to 'full-compaction', please execute this method regularly to produce changelog.

Throws:

Exception

withMetricRegistry

TableWrite withMetricRegistry(MetricRegistry registry)

Set MetricRegistry to table write.
