[SOLVED] Connection pool timeout in cloudant ( via ektorp)

Connection pool timeout in cloudant ( via ektorp)

I am using cloudant and ektorp for DB operations in my java application. When I try to do a load test for 100 users (concurrent hits), it throws

Caused by: org.ektorp.DbAccessException: org.apache.http.conn.ConnectionPoolTimeoutException: Timeout waiting for connection
        at org.ektorp.util.Exceptions.propagate(Exceptions.java:19)
        at org.ektorp.http.StdHttpClient.executeRequest(StdHttpClient.java:146)

Following is my couchdb.properties file

url=https://myaccount.cloudant.com:443
host=https://myaccount.cloudant.com
port=443
username=myusername
password=mypassword
relaxedSSLSettings=true
enableSSL=true
maxConnections=100
connectionTimeout=3000
socketTimeout=30000
autoUpdateViewOnChange=true
cleanupIdleConnections=true

I am using the following code for creating connector

CouchDbConnector dbConnector = couchdbInstance.createConnector(
                    xxxx,true);
dbConnector.queryView(query,test.class);

Please help me understand why I get connection timeout and what param i might need to change inorder to fix this

Solution

By default, multitenant Cloudant accounts are limited to 30 concurrent connections per backend node (typically 3, so 90 concurrent connections). If you need more, reach out to the team at support@cloudant.com and we can increase your concurrent connections limit.
