Subject: Reduce the amount of heap memory required to store many schemas by storing
X-Git-Tag: version-3.12.0~113
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=862acaa3f40c4c56c0b523b0f907853777c12755;p=thirdparty%2Fsqlite.git

Reduce the amount of heap memory required to store many schemas by storing
the column datatype appended to the column name (with a \000 separator),
rather than in separate memory allocation.
