Re: I have question about Sybase ASE 15.7 Partitioning

Hi Mark,

One more quick question....hopefully...

 

Would you recommend putting the local index into the same partition as where the data is going?

 

For instance, I have the audit_event table partitioned with a partition name of event_M72015 that represents data for the month of July, and resides in segment infraaudit2015seg.

 

If I create a local index on the audit_event table, and provide it with the same partition name of event_M72015 and segment name infraaudit2015seg, I am then assuming that both the index and data will reside in the same partition and segment.

 

I'm worried that this may not be good for performance and I/O operations.  I have read Sybase documentation and some technical white papers, but none of them talk specific about isolating the indexes from the data in separate partitions.  I could of missed it somewhere though.....

 

So I'm considering placing the index into a separate partition name, but same segment.  So for example, the local index would be in the idx1_event_M72015 partition (a new partition for the index), but the same segment of infraaudit2015seg.

 

Appreciate any thoughts on the matter!  thanks!

Lisa
