Subject [jira] [Commented] (CASSANDRA-16806) Allow DELETE and TRUNCATE to work on Virtual Tables if the implementation allows it
Date Tue, 31 Aug 2021 10:43:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-16806?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17407236#comment-17407236

Aleksei Zotov commented on CASSANDRA-16806:
-------------------------------------------

[~blerer]

I updated the PR with all the changes. Could you please take a look and provide some feedback.

 

Summary of the PR:
 * implemented TRUNCATE support
 * implemented DELETE support
 * added a restriction for custom timestamps
 * updated unit tests
 * added {{SimpleWritableVirtualTable}} for easier implementation of new VTs

 

What is not in the PR:
 * support for complex type cell deletes 
 * restrictions for static columns, secondary indexes and materialized views (at least need
to check that they exist, I found none of them)

I'd like to address these items while working on VTs for auth caches.

> {{TRUNCATE}} statements are currently not supported by Virtual Tables. For some Virtual
Tables it makes sense to allow it.
> It can be done by adding a {{truncate}} method to the {{VirtualTable}} interface and
calling that method from {{TruncateStatement}}. The default implementation of the method should
be to fire an {{InvalidRequestException}} saying that truncate is not supported on that specific
table.
