-------------------------------------
[~boroknagyz] I am about to start documenting the ACID table support. So, in
3.3, Impala only supports inserting into already existing Hive insert-only ACID
table?
> Implement INSERT for insert-only ACID tables

> Project: IMPALA
> Issue Type: New Feature
> Reporter: Zoltán Borók-Nagy

> Priority: Critical
> Labels: impala-acid
> Fix For: Impala 4.0, Impala 3.3.0
>
>
> Impala should support insertion for insert-only ACID tables.
> For this we need to allocate a write ID for the target table, and write the
> data into the base/delta directories.
> INSERT operation should create a new delta directory with the allocated write
> ID.
> INSERT OVERWRITE should create a new base directory with the allocated write
> ID. This new base directory will only contain the data coming from this
> operation.
