Summary: The current SQL query that checks table existence is under optimized
on big database
Key: ISPN-2454
URL: https://issues.jboss.org/browse/ISPN-2454
Project: Infinispan
Issue Type: Enhancement
Components: Loaders and Stores
Affects Versions: 5.1.0.FINAL
Reporter: Nicolas Filotto
Assignee: Mircea Markus
Last year I proposed an enhancement allowing to use the implicit db schema to ease life of
end-user, unfortunately it seems that it affects the startup time of the product when the
tables contain a lot of rows. Indeed the query can take several seconds to return a
result.
The idea of this task would be to optimize this query for all supported databases in order
to avoid this drawback.

---------------------------------------
It seems that the Query for MS SQL doesn't work on MS SQL 2008 R2, it should be
{code}
SELECT count(*) from (SELECT TOP (1) 1 as C FROM " + tableName + ") T
{code}
The current SQL query that checks table existence is under optimized
on big database
