This was a trivial change, as we needed to add the dictionary to the stream when we encounter it, and then read the next message until we reach a record batch. I tested with the 0.14.1 golden file, I'm going to test with later versions (1.0.0-littleendian) when I get to `arrow::ipc::MetadataVersion::V5` support, hopefully soon.

However, `tokio::spawn` returns a task / future, which `tokio` runtime will then schedule on its thread pool. Therefore, there is no need to limit the number of tasks to the number of logical threads, as tokio's runtime itself is responsible for that work. In particular, since we are using [`rt-threaded`](https://docs.rs/tokio/0.2.22/tokio/runtime/index.html#threaded-scheduler), tokio already declares a thread pool from the number of logical threads available. This PR removes the coupling, in `mergeExec`, between the number of logical threads (`max_concurrency`) and the number of created tasks. I observe no change in performance:

A test that ensures `can_cast_types` and `cast` remain in sync 3. Bug fixes that the test above uncovered (I'll comment inline) 4. Change DataFuson to use `can_cast_types` so that it plans casting consistently with what arrow allows Previously the notions of coercion and casting were somewhat conflated in DataFusion. I have tried to clarify them in https://github.com/apache/arrow/pull/8399 and this PR. See also https://github.com/apache/arrow/pull/8340#discussion_r501257096 for more discussion. I am adding this functionality so DataFusion gains rudimentary support `DictionaryArray`. Codewise, I am concerned about the duplication in logic between the match statements in `cast` and `can_cast_types. I have some thoughts on how to unify them (see https://github.com/apache/arrow/pull/8400#discussion_r504278902), but I don't have time to implement that as it is a bigger change. I think this approach with some duplication is ok, and the test will ensure they remain in sync.

It supports the following (no complete test coverage yet): * writing primitives except for booleans and binary * nested structs * null values (via definition levels) It does not yet support: - Boolean arrays (have to be handled differently from numeric values) - Binary arrays - Dictionary arrays - Union arrays (are they even possible?) I have only added a test by creating a nested schema, which I tested on pyarrow. ```jupyter # schema of test_complex.parquet a: int32 not null b: int32 c: struct> not null child 0, d: double child 1, e: struct child 0, f: float ``` This PR potentially addresses: * https://issues.apache.org/jira/browse/ARROW-8289 * https://issues.apache.org/jira/browse/ARROW-8423 * https://issues.apache.org/jira/browse/ARROW-8424 * https://issues.apache.org/jira/browse/ARROW-8425 And I would like to propose either opening new JIRAs for the above incomplete items, or renaming the last 3 above. ___ **Help Needed** I'm implementing the definition and repetition levels on first principle from an old Parquet blog post from the Twitter engineering blog. It's likely that I'm not getting some concepts correct, so I would appreciate help with: * Checking if my logic is correct * Guidance or suggestions on how to more efficiently extract levels from arrays * Adding tests - I suspect we might need a lot of tests, so far we only test writing 1 batch, so I don't know how paging would work when writing a large enough file I also don't know if the various encoding levels (dictionary, RLE, etc.) and compression levels are applied automagically, or if that'd be something we need to explicitly enable.

charset=UTF-8 Content-Transfer-Encoding: 8bit Note that this PR is deliberately filed against the rust-parquet-arrow-writer branch, not master!! Hi! 👋 I'm looking to help out with the rust-parquet-arrow-writer branch, and I just pulled it down and it wasn't compiling because in 75f804efbfe367175fef5a2238d9cd2d30ed3afe, `schema_to_bytes` was changed to take `IpcWriteOptions` and to return `EncodedData`. This updates `encode_arrow_schema` to use those changes, which should get this branch compiling and passing tests again. I'm kind of guessing which JIRA ticket this should be associated with; honestly I think this commit can just be squashed with https://github.com/apache/arrow/commit/8f0ed91469f2e569472edaa3b69ffde051088555 next time this branch gets rebased. Please let me know if I should change anything, I'm happy to!

Inspired by tests in cpp/src/parquet/arrow/arrow_reader_writer_test.cc These perform round-trip Arrow -> Parquet -> Arrow of a single RecordBatch with a single column of values of each the supported data types and some of the unsupported ones. Tests that currently fail are either marked with `#[should_panic]` (if the reason they fail is because of a panic) or `#[ignore]` (if the reason they fail is because the values don't match). I am comparing the RecordBatch's column's data before and after the round trip directly; I'm not sure that this is appropriate or not because for some data types, the `null_bitmap` isn't matching and I'm not sure if it's supposed to or not. So I would love advice on that front, and I would love to know if these tests are useful or not!

From 3a22d3dd7e0423f71cc325d48e64a1515b45cd8b Mon Sep 17 00:00:00 2001 From: "Carol (Nichols || Goulding)" Date: Thu, 8 Oct 2020 00:16:42 +0200 Subject: [PATCH 22/44] ARROW-10168: [Rust] [Parquet] Schema roundtrip - use Arrow schema from Parquet metadata when available @nevi-me This is one commit on top of https://github.com/apache/arrow/pull/8330 that I'm opening to get some feedback from you on about whether this will help with ARROW-10168. I *think* this will bring the Rust implementation more in line with C++, but I'm not certain. I tried removing the `#[ignore]` attributes from the `LargeArray` and `LargeUtf8` tests, but they're still failing because the schemas don't match yet-- it looks like [this code](https://github.com/apache/arrow/blob/b2842ab2eb0d7a7a633049a5591e1eaa254d4446/rust/parquet/src/arrow/array_reader.rs#L595-L638) will need to be changed as well. That `build_array_reader` function's code looks very similar to the code I've changed here, is there a possibility for the code to be shared or is there a reason they're separate?

Support was added a few years ago in Parquet, and the C++ implementation supports writing null arrays. The array is stored as an int32 which has all values set as null. In order to implement this, we introduce a `null -> int32` cast, which creates a null int32 of same length. Semantically, the write is the same as writing an int32 that's all null, but we create a null writer to preserve the data type.
