BUFFER_POOL_LIMIT query option Defines a limit on the amount of memory that a query can allocate from the internal buffer pool. The value for this limit applies to the memory on each host, not the aggregate memory across the cluster. Typically not changed by users, except during diagnosis of out-of-memory errors during queries.

The default setting for this option is the lower of 80% of the MEM_LIMIT setting, or the MEM_LIMIT setting minus 100 MB.

If queries encounter out-of-memory errors, consider decreasing the BUFFER_POOL_LIMIT setting to less than 80% of the MEM_LIMIT setting.
