Steven Hawkins commented on TEIID-3390:
---------------------------------------
Changes include:
More cleanup - calls to the autocleanuputil from the buffer cleaner and when disk runs out
we'll make a last ditch effort to clear references
Faster cleanup - persisted lobs are associated with the command that creates them and all
will be removed when the command completes
Sizing adjustments - the max lob memory size will now nominally be 32KB rather than 8KB
and buffer creation was adjusted to be initially small and grow on demand
Inclusion rather than inlining - up to some limits the values of subexpressions will be
included rather than inlined via recopying
In total this will reduce the disk consumed and speed up processing.
Improve SQL/XML generation performance and limit disk usage

Key: TEIID-3390
URL:
https://issues.jboss.org/browse/TEIID-3390
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.11
Deeply nested large xml documents generated by SQL/XML can create a lot of temporary disk
backed objects. These objects can have slow cleanup based upon when their references get
cleared.
