For now it consists of only:
using int128_t = __int128;
using uint128_t = unsigned __int128;
All new privitive data types should go into this file in the future.
This commit also adds support in TupleHashJoinStep::forwardCPData,
although we currently do not support wide decimals as join keys.
Row estimation to determine large-side of the join is also updated.
2. Set Decimal precision in SimpleColumn::evaluate().
3. Add support for int128_t in ConstantColumn.
4. Set IDB_Decimal::s128Value in buildDecimalColumn().
5. Use width 16 as first if predicate for branching based on decimal width.
cpimport was doing unsigned comparisons for these, but initializing
max to MIN_BIGINT (0x8000000000000002), which is > than any ascii string,
so it would never get set. Changed the init value to 0 for char
types.
cpimport now has the ability to use libmarias3 to read an object from an
S3 bucket instead of a file on local disk.
This also moves libmarias3 to utils/libmarias3.
If the first byte of a char/varchar was > 0x80 then it will break the
min/max values for an extent during cpimport. This patch makes the
min/max compare unsigned and only switches to signed when storing.
In addition send all the LDI / INSERT...SELECT data to cpimport, not
truncated. Let cpimport figure out the truncation point.
cpimport would truncate UTF8 data half way through a character which
would cause problems for functions using that data. This patch
calculates the correct truncation point when inserting the data.
