Refresh

=======

Crate is `eventually consistent`_. Data written with a former statement is

not guaranteed to be fetched with the next following select statement for

the affected rows.

If required a table can be refreshed explicitly in order to ensure

that the latest state of the table gets fetched::

cr> refresh table locations;

REFRESH OK (... sec)

A table is refreshed periodically with a specified refresh interval. By

default, the refresh interval is set to 1000 milliseconds. The refresh interval

of a table can be changed with the table parameter ``refresh_interval`` (see

:ref:`sql_ref_refresh_interval`).
