Thanks for enthusiasm (both on list and off list). I think we're going to
try to do a second meetup later in the summer in the South Bay as well.
Will get back to everyone shortly. Great to see all the interest.
thanks,
Jacques

I may be missing something, but you need to use Buffer::mutable_data()
somewhere in the wrapper. So either provide a function in the wrapper
that calls it, or invoke it during some init s
Also, if you provide me with full instructions on how to reproduce the
linking error, I'm happy to look if I can figure out what is going on.

Hey Saul,
The Buffer returned by Plasma's Create is not owning the memory, the memory
management happens via reference counting through the explicit
PlasmaClient::Release call. The reason why we now return a buffer instead
of a plain pointer and length is so we can support both CPU (MutableBuffer)
Yeah, I am writing C++ code that provides a C wrapper around this. But, how
do I access either the protected mutable_data_ or the inline mutable_data
from my this wrapper?

Hi Wes,
Here goes some inputs on these 2 usecases.
1. The first use case is around calling Watson Services in a scalable
manner using a custom Rest Data Source

hi Sourav,
Do you have prior references for either of these topics / use cases? I
had not heard about them before.
Thanks,
Wes

Hi Jacques,
I can talk about on either of these 2 topics -
1. Using Arrow with IBM Watson Studio for vectorized query processing on
large volume of data
2. Using Arrow for NetCDF data format for supporting scientific data
processing

Hi Jacques,
I could talk about some of the integration with Spark, if you have room for
another.
Thanks,

Hi Jacques,
If it makes sense, I can certainly talk about the JDBC Adapter work I have been
doing and also some of the future enhancements/related bits of work that could
happen surrounding that. Please let me know if this would be useful for the
audience.

Hey All,
It looks like Thumbtack crew offered to host an Arrow meetup for the Arrow
community in San Francisco and one of my colleagues set it up on Meetup.
Sidd and I have been volunteered to do talks but I would really love to
have one or two other speakers as well. Anyone going to be in San Fra

@Kou, we removed that bit, so Buffer::mutable_data is always inline now.
@Saul, you will want to create a C wrapper for arrow::Buffer so you
can manage memory lifetime from C. Depending on the kind of Buffer you
have, it may not be as simple as calling free(...) on its internal
data.

Hi,
It may be wrong but you may need to add -DNDEBUG flag to C
compiler.

Ah, I see I can use garrow_buffer_get_mutable_data from c_glib.

I am in the process of changing over my C wrapper to work with Arrow 0.9.0.
One change is that the plasma APIs now use arrow::Buffer instead of of raw
pointers, in Create and Get.
In my C wrapper for Create, I need to get the mutable data pointer from the
arrow::Buffer, after it is created. Here i
