Sylvain Lebresne updated CASSANDRA-8203:
----------------------------------------
Assignee: Tyler Hobbs (was: Sylvain Lebresne)
> Unexpected null static column

> Key: CASSANDRA-8203

> Project: Cassandra
> Issue Type: Bug

> I'm using static column.
> When I select whole table (with large limit) some of rows contain null static
> column value, but it cannot happen accoring to application logic.
> When I select same row using keys, static column has non-null value as
> expected.
> Schema:

> cqlsh:iss> describe table target_state;
> CREATE TABLE iss.target_state (
> cell ascii,
> host ascii,
> service ascii,
> active ascii,
> cell_etag timeuuid static,
> etag timeuuid,
> states map<ascii, ascii>,
> PRIMARY KEY (cell, host, service)
> ) WITH CLUSTERING ORDER BY (host ASC, service ASC)
