Rasql_Memory leak with Select into when insert with many MDDs

[Bang Pham Huu]

Run the attchment script to test, it will create a collection and insert a dummy data into it as first MDD, then use this query to insert over itself.

After running the query ~ 10 times, the occupied memory can show that it was leak without being released.

rasql -q 'select (char)c into test_1 from test_1 as c' --user rasadmin --passwd rasadmin

@dkamov to check for the leak run this valgrind command:

valgrind —leak-check=full —track-origins=yes —tool=memcheck directql -q 'select (char)c into test_1 from test_1 as c' -d /opt/rasdaman/data/RASBASE —user rasadmin —passwd rasadmin

This is not a memory leak. You're doing the select into 12 times and this is duplicating the arrays in test_1 at each iteration. At the end you have 2¹² arrays and this takes a bunch of memory.
