Compress on a large table fails with IllegalArgumentException - Illegal Capacity
--------------------------------------------------------------------------------
Key: DERBY-4119
URL: https://issues.apache.org/jira/browse/DERBY-4119
Project: Derby
Issue Type: Bug
Components: Store
Affects Versions: 10.5.1.0
Reporter: Kristian Waagan
When compressing a large table, Derby failed with the following exception:
IllegalArgumentException; Illegal Capacity: -X
I was able to access the database afterwards, but haven't yet checked if all
the data is still available.
The compress was started with CALL SYSCS_UTIL.SYSCS_COMPRESS_TABLE('schema',
'table', 1) from ij.
The data in the table was inserted with 25 concurrent threads. This seems to
cause excessive table growth, as the data inserted should weigh in at around 2
GB. The table size after the insert is ten times bigger, 20 GB.
I have been able to generate the table and do a compress earlier, but then I
have been using fewer insert threads.
I have also been able to successfully compress the table when retrying after
the failure occurred (shut down the database, then booted again and compressed).
I'm trying to reproduce, and will post more information (like the stack trace)
later.
So far my attempts at reproducing has failed. Normally the data is generated
and the compress is started without shutting down the database. My attempts
this far has consisted of doing compress on the existing database (where the
failure was first seen).
