Gagan Goel	1a849c88e8	MCOL-5162 This patch allows for an automatic upgrade of syscat tables via dbbuilder. ... We have added a new function, SystemCatalog::upgrade(), which will create a new column in the database and fill it with default values. It uses a reference column to fill the column, which is passed as a std::unordered_map<key, value> value to SystemCatalog::upgrade() function, where key is the target column which needs to be created. In addition, we pass additional std::unordered_map's to SystemCatalog::upgrade() containing information such as the datatypes and colwidths of the target and reference columns, as well as the default value which will be used to fill the target column.	2022-08-15 21:03:13 +00:00

Andrew Hutchings	ffcfc41563	MCOL-507 Further ExeMgr performance improvements ... This does the following: * Switch resource manager to a singleton which reduces the amount of times the XML data is scanned and objects allocated. * Make the I_S tables use the FE implementation of the system catalog * Make the I_S.columnstore_columns table use the RID list cache * Make the extentmap pre-allocate a vector instead of many small allocs	2017-01-16 12:33:27 +00:00
