.Large queries on Parquet objects no longer emit an `Out of memory` error Previously, in some cases, when a query was processed on a Parquet object, that object was read in large chunks. This caused the Ceph Object Gateway to load a larger buffer into the memory, which was too big for low-end machines. The memory would especially be affected when Ceph Object Gateway was co-located with OSD processes, which consume a large amount of memory. With the `Out of memory` error, the OS killed the Ceph Object Gateway process. With this fix, the there is an updated limit for the reader-buffer size for reading column chunks. The default size is now 16 MB and the size can be changed through the Ceph Object Gateway configuration file.
