Hi, I'm trying to understand how does connection pooling works in HBase.
I've seen that
https://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/HConnectionManager.html
is recommended to use.
I have a servlet, it's instance shaed among many threads.
What is a good way to use connection pooling in this case?
Is this
HConnection connection = HConnectionManager.createConnection(config);
HTableInterface table = connection.getTable("table1");
try {
// Use the table as needed, for a single operation and a single thread
} finally {
table.close();
connection.close();
}
1. enough to reuse connection and they wouldn't be opened each time?
2. why do I have to close ALL: table and connection? It's done by design?
