Mac Yang updated HIVE-1910:
---------------------------
Attachment: HIVE-1910.1.patch.txt
This enhancement is more relevant to metastore running in thrift server mode.
With the current code, a long running metastore server could potentially end up
with a large number of objects in memory (most notabl with Partition, SerDeInfo
and StorageDescriptor object).
This patch adds a new config parameter, "hive.metastore.cache.pinobjtypes", to
make object pinning configurable. It also provides default value in
hive-default.xml which will keep the current behavior.
> Provide config parameters to control cache object pining

> The metastore currently pin instances of the following classes in the
> secondary cache,
> MTable, MStorageDescriptor, MSerDeInfo, MPartition, MDatabase, MType,
> MFieldSchema, MOrder.class
> It would be better if this behavior is configurable instead of hard coded.
