https://github.com/edef1c/libfringe This crate has rather nice approach to switching contexts: - instead of saving all callee registers it issues asm to denote they are clobbered. Then the compiler saves only...

[rfc] new scheduler

The current scheduler has the following problems: 1) it needs configuration (workers, io_workers, run_on_io): it would be nicer if user does not need to configure anything and yet get maximum...

http client/server library for may

What's the recommended library for http client/server for may? If none exists perhaps this should be top priority to increase adoption?

way to control the scheduler

5

This can allow some usecases: - for a given coroutine/scope limit parallelism to 1 - pin a coroutine/scope to a specific thread (UI thread for example) Perhaps this is already...

improve memory efficiency/API

Specify a backwards/forward compatible way to extend *any* Thrift struct in Parquet. ref [Parquet Metadata evolution](https://docs.google.com/document/d/1PQpY418LkIDHMFYCY8ne_G-CFpThK15LLpzWYbc7rFU/edit) ### Jira - [x] My PR addresses the following [Parquet Jira](https://issues.apache.org/jira/browse/PARQUET/) issues and references...

1. Add `min8`/`max8` fields for encoding fixed length binary encoding for min/max for physical types less than or equal 8 bytes. 2. Deprecate `ColumnMetaData.encoding_stats` and replace with a bool `ColumnMetaData.is_fully_dict_encoded`'...

1. Make `ColumnMetaData.type` optional 2. Make `ColumnMetaData.path_in_schema` optional 3. Add `ColumnMetaData.schema_index`. This is the ordinal in `FileMetaData.schema` this column corresponds to. This allows sparse representation of columns in a rowgroup....
