------------------------------------
Summary: Give configuration load_catalog_in_background more
fine-grained configuration
Key: IMPALA-12573
URL: https://issues.apache.org/jira/browse/IMPALA-12573
Project: IMPALA
Issue Type: Improvement
Components: Catalog
Reporter: Maxwell Guo
Assignee: Maxwell Guo
As we know if load_catalog_in_background set to true, then the table meta will
load async for catalogd.
During this period when catalogd starts up, if the flag set to true, then all
the table will load async, then the queue will be big . So we may left it to
false by deafult. But if we invalidate some table manually ,we may want them to
load . So I think we can introduce a new flag
load_catalog_in_background_at_startup , we can set
load_catalog_in_background_at_startup to false, and load_catalog_in_background
to true by default.
