index.html
roadmap.html
[~jamestaylor] [~mujtabachohan]
Can you please review? I removed transactions from the roadmap. I also modified
the transactions section in index.html.
> Document transactional behavior

>
> We need to add a new top level page to explain transactions and their
> behavior from the user point of view:
> - How to configure a new/existing table to be transactional (CREATE TABLE and
> ALTER TABLE ... TRANSACTIONAL=true). Also that it's currently a one-way
> street - you cannot make a transactional table non transactional
> (PHOENIX-2439).
> - Transaction implicitly started when first statement run against a
> transactional table
> - Indexes on transactional table are transactional with data table.
> - Exception raised if transaction committed that conflicts (at row level)
> with other committed transaction.
> - Queries do not see commits of other transactions until transaction is ended
> (rolled back or committed).
> - Transaction will see their own updates (read-your-own-write behavior).
> - Requires that transaction manager is started (and how to start it).
> - Various configuration options specific to transactions
> - Invalid list - how it can potentially grow and how to manually clear it if
> necessary.
> - Unsupported behavior: for example, certain TTL behavior, no SCN.
> We also need to adjust existing web pages that currently says we don't
> support full ACID and promote this new capability.
