That is not always true. A block may have a giant dictionary and use only a small subset of values. Please add a note that this is only a heuristic

we can't have giant dictionary blocks here as the dictionary size is limited by page size by the if below.

If dictionary size is almost as big as the block size it will still be slower. Consider adding a coefficient here. Somewhere around 2 probably

Revert 6058b29, then we don't need this factory method
Member

I think this is wrong. You can check for FixedWithType and use the size to know if it's 1/2/4/8/16. This will remove many cases below, and handle IpAddressType that is missed. I think all of the SlicePositionsAppender checks can be replaced with VariableWidthType.

Yeah, makes sense.

remaind me again why we couldn't just isolate this guy (type.appendTo intuitively should be inlined since it's called from single isolated callsite). Please add comment in code.
Member

There was a problem hiding this comment.
actually, we should isolate TypedPositionsAppender. It may or may not help, depending on jit decisions but it won't hurt. I'll fix that.
Why we can't use TypedPositionsAppender for everything? Because Type.appendTo method uses multiple Block types (Dict, RLe, normal) so the calls to Block.IsNull or Block.getLong are mega-morphic and thus Type method body uses virtual calls.
If the Type.appendTo body is inlined in the (isolated) PositionsAppender. appendTo loop, the the call site is not mega-morphic anymore and this works well, but this depends on the inlining decision that is influenced by other factors like compiled method size, byte code size, order of compilation (including the pollution state at the compilation time) etc. and in my experiments it was not happening, even for simple types.

I double-checked the LongPositionsAppender vs isolated TypedPositionsAppender.
TypedPositionsAppender
Benchmark (channelCount) (enableCompression) (nullRate) (partitionCount) (positionCount) (type) Mode Cnt Score Error Units
BenchmarkPartitionedOutputOperator.addPage 1 false 0.2 16 8192 BIGINT avgt 10 1349.558 ± 16.764 ms/op

LongPositionsAppender
Benchmark (channelCount) (enableCompression) (nullRate) (partitionCount) (positionCount) (type) Mode Cnt Score Error Units
BenchmarkPartitionedOutputOperator.addPage 1 false 0.2 16 8192 BIGINT avgt 10 1022.218 ± 17.139 ms/op
The reason for the perf difference is that although most of the AbstractLongType.appendTo is inlined into TypedPositionsAppender, there is still a virtual call to Block.isNull (see the jitwatch call chain screens below). The reason for the inline failure is <inline_fail reason="virtual call"/>
<parse method="1259" stamp="30.717" uses="26103.000000">

<inline_fail reason="virtual call"/>
The TypedPositionsAppender isolation is forced with code below, that is used per input Block class but still, there are DictionaryBlock calls there even though dictionary is not part of the benchmarked type (but used to pollute the profile)
private PositionsAppender createAppender(Type type)
{
Class<? extends PositionsAppender> appenderClass = findDedicatedAppenderClassFor(type);
if (***appenderClass == null || true***) {
return isolateTypeAppender(type);

That should be Class<? extends Block>. You should extract block types from all children using io.trino.spi.block.Block#getChildren

Do you mean List< Class<? extends Block>>? This version does not support complex types like RowType or MapType so this won't help.
For RowType support, this would probably be some kind of tree unless we don't care about the lower level nesting.

lgtm
In the future, we might consider moving io.trino.spi.type.Type#appendTo to TypeManager which would allow us to overload different batch appendTo methods.
For example, we could have:
@BatchOperator(APPEND_TO)
void appendTo(@SqlType(StandardTypes.BIGINT) LongArrayBlock block, BlockBuilder builder) {
...
}
@BatchOperator(APPEND_TO)
void appendTo(@SqlType(StandardTypes.BIGINT) RunLengthEncoded block, BlockBuilder builder) {
...
}

Description
Add PagePartitioner implementation that copies pages column-wise.
The implementation switches to the old row-wise approach for cases where it's not beneficial to go column-wise.
