[I] add updateDocuments(Term, ColumnBatch) to IndexWriter for atomic delete-and-add columnar operations [lucene]
iprithv opened a new issue, #16117:
URL: https://github.com/apache/lucene/issues/16117
### Description
The experimental columnar indexing API (`IndexWriter.addBatch(ColumnBatch)`) added supports bulk columnar document addition, but there is no equivalent to `updateDocuments(Term, Iterable)`
for columnar batches. Users who index via columns cannot atomically delete existing documents by term
and add a new columnar batch in a single operation.
add the following public methods to `IndexWriter`
```java
/**
* Atomically deletes documents matching the provided term and adds a batch of documents
* in column-oriented format.
*/
public long updateDocuments(Term delTerm, ColumnBatch columnBatch) throws IOException;
/**
* Similar to above but takes a Query instead of a Term.
*/
public long updateDocuments(Query delQuery, ColumnBatch columnBatch) throws IOException;

Hi, I’d like to take this issue if nobody is already working on it. I’ll look into adding the ColumnBatch variants of updateDocuments for both Term and Query deletes, along with tests covering the atomic delete-and-add behavior.

before I work on this, @Tim-Brooks @ChrisHegarty tagging you as you worked on #15990. Would appreciate your input, thanks!
1. Should the methods be `updateDocuments(Term, ColumnBatch)` (overloading the existing row-oriented name) or `updateBatch(Term, ColumnBatch)` (new name matching `addBatch`)?
2. Should both `Term` and `Query` deletion variants be included, or just `Term` to start?
3. Should `softUpdateDocuments(Term, ColumnBatch, Field... softDeletes)` also be added for parity with the row-oriented `softUpdateDocuments(Term, Iterable, Field...)`?
