SQL Server 2008 R2 Tips

Δεν ξέρω αν είχατε την δυνατότητα να δείτε τα δύο poster που έχω φτίαξει για τις δυνατότητες του SQL Server 2008 R2.

Φτιάχνοντας τα εντόπιζα πράγματα τα οποία με εντυπωσίαζαν. Αυτά που μου έκαναν περισσότερη εντύπωση ήταν δύο.

1. Το πόσους SQL Servers μπορώ να διαχειριστώ σε multi-instance management;

Η απάντηση είναι 250 στην Datacenter edition και 25 στην Enterprise.

2. To πόσους indexes μπορώ να έχω σε ένα πίνακα;

Μέχρι την έλευση του SQL Server 2008 R2 είχα την δυνατότητα να έχω 250 indexes σε κάθε πίνακα (1 clustered + 249 nonclustered). Στο SQL Server 2008 R2 σε όλες τις εκδόσεις έχω 1000 indexes!!!!! (1 clustred + 999 nonclustred). Είμαι περίεργος να δω ποιος θα βάλει τόσους indexes σε ένα πίνακα.
