Community Over Code Asia 2024 Travel Assistance Applications now open!
Hello to all users, contributors and Committers! The Travel Assistance Committee (TAC) are pleased to announce that travel assistance applications for Community over Code Asia 2024 are now open! We will be supporting Community over Code Asia, Hangzhou, China July 26th - 28th, 2024. TAC exists to help those that would like to attend Community over Code events, but are unable to do so for financial reasons. For more info on this year's applications and qualifying criteria, please visit the TAC website at < https://tac.apache.org/ >. Applications are already open on https://tac-apply.apache.org/, so don't delay! The Apache Travel Assistance Committee will only be accepting applications from those people that are able to attend the full event. Important: Applications close on Friday, May 10th, 2024. Applicants have until the the closing date above to submit their applications (which should contain as much supporting material as required to efficiently and accurately process their request), this will enable TAC to announce successful applications shortly afterwards. As usual, TAC expects to deal with a range of applications from a diverse range of backgrounds; therefore, we encourage (as always) anyone thinking about sending in an application to do so ASAP. For those that will need a Visa to enter the Country - we advise you to apply now so that you have enough time in case of interview delays. So do not wait until you know if you have been accepted or not. We look forward to greeting many of you in Hangzhou, China in July, 2024! Kind Regards, Gavin (On behalf of the Travel Assistance Committee)

Re: [DISCUSS] Flight RPC: add 'fallback' URI scheme
Thanks for the comments - I've updated the implementation [1] and added Go + integration tests. If this all checks out I'd like to start a vote soon.

Filtering on arrow::DictionaryArray column
Hello, I have an arrow::RecordBatch where one of the column called id is arrow::DictionaryArray. I wanted to only read the rows which have value, let's say "specialValue", in "id" column. I have some ad hoc code to read the rows one by one and apply the filter manually but I am wondering if there is a way to filter a RecordBatch by a column value and get a filtered RecordBatch. Thanks, Vaneet
