Re: Storm topology using all the Max connections of db
Hi! Well is seems that you have to contact the team that created the jdbc storm project. It seems that the issue is deeper than my knowledge. I hope that my advises helped you. If you have a solution, please share it here that the others can benefit from your experience. Good luck!

Re: Storm topology using all the Max connections of db
Hi,
I'm closing up and opening the connections after execution of insert query
by my bolt.Do I need to increase the max connections db to a level of 500
to 1000? Here in log file of supervisor it tells me the connection made by
bolt is closed and again taking new connection.I think after closing it is
going into ideal and not used for new connections.

Re: Storm topology using all the Max connections of db
Hi,
I just added
a statement
* // config.setMaximumPoolSize(50);*
public synchronized void prepare() {
if(dataSource == null) {
Properties properties = new Properties();
properties.putAll(configMap);
HikariConfig config = new HikariConfig(properties);
* config.setMaximumPoolSize(50);*
this.dataSource = new HikariDataSource(config);
this.dataSource.setAutoCommit(false);
}
}
and I'm getting the following error

Hi Spico,
I use 9 bolts with parallelism of 1 and with 1 task for each
bolt(default) and I'm not using any ConnectionPool for connecting to
postgres.Just using jdbc classe examples here is source example
http://storm.apache.org/releases/2.0.0-SNAPSHOT/storm-jdbc.html.
I will check by using the ConnectionPool.
Thank you.

Hi Spico, I use 9 bolts with parallelism of 1 and with 1 task for each bolt(default) and I'm not using any ConnectionPool for connecting to postgres.Just using jdbc classe examples here is source example http://storm.apache.org/releases/2.0.0-SNAPSHOT/storm-jdbc.html.

Re: Storm topology using all the Max connections of db
Hello! How many tasks do you have for inserting the data to your database? Are you using ConnectionPool for connecting to Postgres? If your number of task superseeds the number of max connections provided in connection pool then your have a problem. Please also check the number of max connections that your db accepts. I hope that these help.
