Limitations

In this section of the manual, some of the hard limits of the RaimaDB database system will be documented. There are practical limits, like performance or disk space that may be reached before any hard limits are hit.

Row Size

It is recommended that the total row size (sum of the column sizes) should not exceed 16K bytes. The size limit does not include any BLOB or CLOB columns.

The size of CHAR columns equals the number of characters multiplied by 4 plus one for the null byte string terminator.

There is no hard limit imposed on the number of columns per table or the size of those columns. However, the practical limit of 16K bytes per row does limit the potential size of the individual columns.

Key Size

The size of a key should not exceed 16K bytes in size.
