Review comment:
Check it out. Most of the time, they were all ending with INT1. There is
a couple of double and text too.

> Affects Versions: 5.0.0, 4.15.0, 4.14.3
> Reporter: Geoffrey Jacoby
> Assignee: Gokcen Iskender
> Priority: Blocker
> Fix For: 5.1.0, 4.16.0

> 1. Create a table T
> 2. Create a view V that extends the PK of T, where the last field of the
> view's PK is a fixed width column C such as an INTEGER or BIGINT
> 3. Create a view index VI on V that does NOT contain C in its index key
> 4. Select C from the view with a query that runs against the view index
> You will get the following error:
> {code:java}
> java.sql.SQLException: ERROR 201 (22000): Illegal data. Expected length of
> at least 8 bytes, but had 7
> {code}
> [~giskender], [~kadir], [~tkhurana] and I investigated. It appears the
> problem comes from
> IndexMaintainer.buildRowKey:707-713
> {code:java}
> int length = stream.size();
> int minLength = length - maxTrailingNulls;
> byte[] indexRowKey = stream.getBuffer();
> // Remove trailing nulls
> while (length > minLength && indexRowKey[length-1] ==
> QueryConstants.SEPARATOR_BYTE) {
> length--;
> }
> {code}
> The logic to remove trailing separator bytes shouldn't run if the end of the
> index key (i.e the end of the base PK) is a fixed width column. Otherwise,
> we'll truncate whenever the last byte of the fixed width field happens to be
> \x00
>
> This only happens for view indexes (mutitenant or not)
