Hi!
As discussed in #6815 and have atomic RETURNING (records are first
changed, then returned) I'd want to implement local temporary tables,
initially only in BLR level.
I don't want to discuss user visible complete local temporary tables
feature here, that will make #6815 stuck.
It will be necessary to add:
blr_dcl_local_table - declares a local table.
It will have a blr version for future improvements, an id and list of
fields and they types.
blr_local_table_id - references a local table by its id
blr_local_table_truncate - truncate a local table
blr_local_table_id should be supported at least in blr_rse and blr_store*
Hmm... LTT is good to have, but... is it necessary here ?
Is it possible to use RecordBuffer (and some kind of BufferedStream) for
temporary storage ?
Data will be placed in temp space.
Sure.
