Description

The proposed fix changes default Precision and DisplaySize configured for TIME and DATE types.

OpenSearchType(JDBCType jdbcType, Class<?> javaClass, int precision,
int displaySize, boolean isSigned) {

Precision is the third arg and DisplaySize is the fourth arg.


DATE(JDBCType.DATE, Date.class, 10, 10, false),
TIME(JDBCType.TIME, Time.class, 8, 8, false),

Please, note, classes referenced here ^ are java.sql.* classes, not java.time.* ones. Time has no fraction seconds part.

I just had a general question. What unit of measurement are precision and size (i.e., is it the number of bits, bytes, digits, etc... )?

I just had a general question. What unit of measurement are precision and size (i.e., is it the number of bits, bytes, digits, etc... )?

According to docs:

For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component)

DATE(JDBCType.DATE, Date.class, 24, 24, false),
TIME(JDBCType.TIME, Time.class, 24, 24, false),
DATE(JDBCType.DATE, Date.class, 10, 10, false),
TIME(JDBCType.TIME, Time.class, 8, 8, false),
DATETIME(JDBCType.TIMESTAMP, Timestamp.class, 24, 24, false),
TIMESTAMP(JDBCType.TIMESTAMP, Timestamp.class, 24, 24, false),

Should we update DATETIME and TIMESTAMP to a precision of 9?
