Remaining work for first release

[xqrzd]

This issue tracks all remaining missing features before this library will be published. This list is incomplete, and will be extended.

Needed for first alpha/beta release:

• General fault tolerance
• Authz token support
• Decide on library name (currently leaning towards Knet.Kudu.Client)
• Implement logging (with LibLog deprecated, leaning towards Microsoft.Extensions.Logging)
• Ensure client timestamp propagation is working properly
• Ensure exactly-once RPCs are working properly
• API review
• Fix session
• Rework table builder (plus support for setting comments, default read/write values)
• CancellationToken support
• Optimize key encoding, and verify vectorized implementation
• Account for changing range partitions in WriteAsync
• Send required features for relevant RPCs
• Alter table support
• Capture deserialization errors, and throw them from KuduConnection.SendReceiveAsync
• Add default value to ColumnSchema
• Support setting date default value

Needed for first stable release:

• Add more tests
• KuduRpc cleanup
• Scanner cleanup
• Scan tokens
• Scanner auto-mapper (via expression trees)
• Fault tolerant scanners
• Per-tserver queue session (future)
• Improve exception stack trace (avoid large recursive stack trace)
• Scanner keep-alive
• Expose scan metrics
• Enhance tablet cache so it can be used for scan tokens
• KuduPredicate cleanup + optimizations
• Final API review
• Documentation
• Expose session errors
• Expose partitioner
• Refactor parsing logic
• [assembly: CLSCompliant(true)]

hi @xqrzd ,

Thanks!

I forgot to update the readme, the first preview release is available here, https://www.nuget.org/packages/Knet.Kudu.Client
I'm hoping to have a stable release within the next few months, but continue publishing preview versions along the way.

Thanks for the update! Looking forward for more preview versions :)
