The following functions should be implemented (should not raise SQLFeatureNotSupportedException when called with supported resultSetHoldability value, referenced as holdability below):

• createStatement(type, concurrency, holdability)
• prepareCall(sql, type, concurrency, holdability)
• prepareStatement(sql, type, concurrency, holdability)

Also the following methods should be supported:

• getHoldability()
• setHoldability(holdability)

The DatabaseMetaData.supportsResultSetHoldability(holdability) should return appropriate values for both ResultSet.HOLD_CURSORS_OVER_COMMIT and ResultSet.CLOSE_CURSORS_AT_COMMIT. The DatabaseMetaData.getResultSetHoldability() should return a default holdability: one of two values above.

The issue is about proper APIs support, so it seems that one of the holdability values support is enough. It depends of Tarantool/SQL cursors implementation or, maybe, cursors emulation support of the driver.
