<h2>Improvements For Partitions</h2>

<p>Now it's possible to ATTACH a partition or a part
<br/>with a <span style="color: green;">different partition key!</span></p>

<p>Examples: you created an excessively granular partition key,<br/>and want to simplify it or remove the partition key whatsoever.</p>

<!--
SHOW CREATE TABLE hits;
CREATE TABLE hits2 AS hits ENGINE = MergeTree PRIMARY KEY (CounterID, EventDate, UserID, EventTime, WatchID) PARTITION BY EventDate;
ALTER TABLE hits2 ATTACH PARTITION () FROM hits
INSERT INTO hits2 SELECT * FROM hits LIMIT 1000000;
CREATE TABLE hits3 AS hits ENGINE = MergeTree PRIMARY KEY (CounterID, EventDate, UserID, EventTime, WatchID);
SELECT DISTINCT partition FROM system.parts WHERE table = 'hits2';
ALTER TABLE hits3 ATTACH PARTITION '2013-07-15' FROM hits2;
