Christian Spriegel updated CASSANDRA-13086:
-------------------------------------------
Description:
Every now and then I see a ResultSet for one of my CAS queries that contain
wasApplied=false, but does not contain my value column.
I just now found another occurrence, which causes the following exception in
the driver:
{code}
...
Caused by: com.mycompany.MyDataaccessException: checkLock(ResultSet[ exhausted:
true, Columns[[applied](boolean)]])
at com.mycompany.MyDAO._checkLock(MyDAO.java:408)
at com.mycompany.MyDAO._releaseLock(MyDAO.java:314)
... 16 more
Caused by: java.lang.IllegalArgumentException: value is not a column defined in
this metadata
at
com.datastax.driver.core.ColumnDefinitions.getAllIdx(ColumnDefinitions.java:266)
at
com.datastax.driver.core.ColumnDefinitions.getFirstIdx(ColumnDefinitions.java:272)
at
com.datastax.driver.core.ArrayBackedRow.getIndexOf(ArrayBackedRow.java:81)
at
com.datastax.driver.core.AbstractGettableData.getBytes(AbstractGettableData.java:151)
at com.mycompany.MyDAO._checkLock(MyDAO.java:383)
... 17 more
{code}
The query the application was doing:
delete from "Lock" where lockname=:lockname and id=:id if value=:value;
I did some debugging recently and was able to track these ResultSets to
StorageProxy.cas() to the "CAS precondition does not match current values {}"
return statement.
