<story><title>Polars: Company Formation Announcement</title><url>https://www.pola.rs/posts/company-announcement/</url></story><parent_chain></parent_chain><comment><author>infogulch</author><text>One of the interesting components of Polars that I&amp;#x27;ve been watching is the use of the Apache Arrow memory format, which is a standard layout for data in memory that enables processing (querying, iterating, calculating, etc) in a language agnostic way, in particular without having to copy&amp;#x2F;convert it into the local object format first. This enables cross-language data access by mmaping or transferring a single buffer, with zero [de]serialization overhead. Something genius and obvious in hindsight.&lt;p&gt;For some history, there has been a bit of contention between the official arrow-rs implementation and the arrow2 implementation created by the polars team which includes some extra features that they find important. I think the current status is that everyone agrees that having two crates that implement the same standard is not ideal, and they are working to port any necessary features to the arrow-rs crate and plan on eventually switching to it and deprecating arrow2, but it will take some time to get there.&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;apache&amp;#x2F;arrow-rs&amp;#x2F;issues&amp;#x2F;1176&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;apache&amp;#x2F;arrow-rs&amp;#x2F;issues&amp;#x2F;1176&lt;/a&gt;&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;jorgecarleitao&amp;#x2F;arrow2&amp;#x2F;pull&amp;#x2F;1476&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;jorgecarleitao&amp;#x2F;arrow2&amp;#x2F;pull&amp;#x2F;1476&lt;/a&gt;</text></comment>
