Changeset: be2db7647a0e for MonetDB
URL: https://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=be2db7647a0e
Modified Files:
sql/server/rel_sequence.c
Branch: Aug2018
Log Message:
Improve the calculation of the buffer size for storing the generated sequence
names.
It used to compute a size of 1067, now 15. This reduces the size of allocated
memory considerably.
TODO: change the api of function: int store_next_oid(void) in store.c to oid
store_next_oid(void). This needs to be done in default branch.
