Hi,
I didn't upload release notes and documentation for 6.0.2,
7.0.1 and 8.0.1 because they are irregular releases for us:
* We don't recommend users expect Go users to use 6.0.2,
7.0.1 and 8.0.1.
Reasons:
* There are no differences with 6.0.1&6.0.2, 7.0.0&7.0.1,
8.0.0&8.0.1 except the
Hi,
Why do we ignore PRs from dependabot?
Generally, dependabot is useful to avoid security

Hi Laurent,
I agree that there is a common pattern in converting row-based formats to
Arrow.
Imho the difficult part is not to map the storage format to Arrow
specifically - it is to map the storage format to any in-memory (row- or
columnar- based) format, since it requires in-depth knowledge
Let me clarify the proposal a bit before replying to the various previous
feedbacks.
It seems to me that the process of converting a row-oriented data source
(row = set of fields or something more hierarchical) into an Arrow record
repeatedly raises the same challenges. A developer who must
Yea, the drawback you'll find there is that you can't effectively stream
record batches as they are available with that setup as you wait for all of
the results before converting to an Arrow table.
The result is higher memory usage necessary for larger result sets and your
time to the first byte
Correct more or less.. It is Arrow Flight Native end to end.
The GraphQL query is a string (saved as a Flight Ticket) that is sent from a
client using Arrow Flight RPC.
The GraphQL query is executed on the GraphQL flight server that produces python
record objects (JSON structured records).
So this is sightly different than what I was doing and spoke about. As far
as I can tell from your links, you are evaluating the graphql using that
graphql server and then converting the JSON response into arrow format
(correct me if I'm wrong please).
What I did was to hook into a graphql parser
We had an e-mail thread about this in 2018
https://lists.apache.org/thread/35pn7s8yzxozqmgx53ympxg63vjvggvm
I still think having a canonical in-memory row format (and libraries
to transform to and from Arrow columnar format) is a good idea — but
there is the risk of ending up in the tar pit of
I'm working on something similar for Ariadne which is a python graphql server
package.

Are there more details on what exactly an "Arrow Intermediate
Representation (AIR)" is? We've talked about in the past maybe having a
memory layout specification for row-based data as well as column based
data. There was also a recent attempt at least in C++ to try to build
utilities to do these
I think this has been addressed for both Parquet and Python to handle records
including nested structures. Not sure about Rust and Go..

Hi all,
@Neal, I have also already assigned myself to ARROW-15691, for updating archery
to work with a default branch named ‘master’ or ‘main’, and will prioritize
this task.
Thank you,

Dears:
In some situations, exists the following requirement, get the
binary array slice in byte unit, like start from 0 , end to 10, step 1, it
will take 10 bytes
till now , only found in code unit, is there any plan to develop it ? thanks
