Partitioning: When partition pruning on an
NDBtable resulted in an ordered index scan spanning only one partition, any descending flag for the scan was wrongly discarded, causing
ORDER BY DESCto be treated as
ORDER BY ASC,
MAX()to be handled incorrectly, and similar problems. (Bug #33061)
When all data and SQL nodes in the cluster were shut down abnormally (that is, other than by using
STOPin the cluster management client), ndb_mgm used excessive amounts of CPU. (Bug #33237)
When using micro-GCPs, if a node failed while preparing for a global checkpoint, the master node would use the wrong GCI. (Bug #32922)
Under some conditions, performing an
ALTER TABLEon an
NDBCLUSTERtable failed with a Table is full error, even when only 25% of
DataMemorywas in use and the result should have been a table using less memory (for example, changing a
VARCHAR(80)). (Bug #32670)
