Bug ID: 54537
Summary: StatementFinalizer closeInvoked is too slow for large
batch jobs.
Product: Tomcat Modules
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: critical
Priority: P2
Component: jdbc-pool
Assignee: dev@tomcat.apache.org
Reporter: kristo.kuusk...@nortal.com
Classification: Unclassified
We had a transaction with 6 million statements. In the end of transaction
org.apache.tomcat.jdbc.pool.interceptor.closeInvoked was called and it ran for
couple of hours before we terminated it.
The problem is that code below is basically O(n^2) and takes too much time with
large amount of statements.
Solution: use more suitable Collection type for statements or change the cycle
logic (for i=...).
while (this.statements.size() > 0) {
WeakReference ws = (WeakReference)this.statements.remove(0)
