---------------------------------
Summary: Slower dataimport process caused by not reusing jdbc
connections
Key: SOLR-5954
URL: https://issues.apache.org/jira/browse/SOLR-5954
Project: Solr
Issue Type: Bug
Components: contrib - DataImportHandler
Affects Versions: 4.7.1
Reporter: Paco Garcia
Priority: Minor
Fix For: 4.8, 4.7.2
Hi,
SOLR-5734 introduced a regression that causes that the connections used in the
dataimport process were closed and reopen in every sql.
The change to nanoTime in the method getConnection of JdbcDataSource.java
forgot to convert the timeout used to reuse the connection.
The constant CONN_TIME_OUT must be changed to nanos to be compared. (*1000*1000)
private Connection getConnection() throws Exception {
long currTime = System.nanoTime();
if (currTime - connLastUsed > CONN_TIME_OUT) {<<<<<<<<<<<<<<<
synchronized (this)
{ Connection tmpConn = factory.call(); closeConnection(); connLastUsed =
System.nanoTime(); return conn = tmpConn; }
} else
{ connLastUsed = currTime; return conn; }
}
private static final long CONN_TIME_OUT = 10 * 1000; // 10 seconds
Regards
