Key: DERBY-1062
URL: http://issues.apache.org/jira/browse/DERBY-1062
Project: Derby
Type: Improvement
Components: SQL, Store, Newcomer
Versions: 10.1.2.2
Reporter: Mike Matrigali
Priority: Minor
Change the internal implemetation of SYSCS_INPLACE_COMPRESS_TABLE to share
existing alter table
code. One suggested approach is to use the same mechanism as
SYSCS_COMPRESS_TABLE. Such
an implementation would involve:
o change the parser for alter table to accecpt some internal only syntax for
SYSCS_INPLACE_COMPRESS_TABLE
o change the alter table constant action to get the required information for
inplace compress
o move most of the inplace compress driving code to a routine in alter table
execution, following the same
coding pattern as existing alter table compress.
I believe doing this will have multiple benefits:
1) shares existing alter table code, so things like error checking, security
management, ... is all done by one piece of code
2) by sharing the code I believe the following outstanding JIRA issues will be
addressed: DERBY-719, DERBY-720 -
3) future changes addressing ddl like grant/revoke will automatically work.
