“Combining records in order to reduce number of records in a feature class”

We’ve a feature class that contains walls (line features). Each wall consists from multiple number of lines which leads to have around 800000 records. This high number of records causes a significant delay in performance. We’re trying to reduce the number of features by combining records together. How we can achieve this in the least time possible.

Thanks,

Alaa

Thanks Dan, Dissolve worked great with us and the performance improved Significantly. I was able to reduce the number of records to only 79.

What kinds of performance problems are you having?  Drawing slowness?  Drawing slowness can be just as much, if not more, impacted by vertex density as it can by the total number of records.  The screenshot you show doesn't appear to have that many records in it, if it draws slow at that scale, I would look into whether reducing vertices is an option:  About simplifying and smoothing a feature—Help | ArcGIS Desktop

Thanks all for your suggestions.

Actually its very slow when trying to transfer the data (using copy ) and also when displaying the features.

Given the size of the file, it may be your computer.  Have you tried to improve the settings using available options?

And have you tried to dissolve to see if it improves the load time?

It was taking a very long time to copy the data from mdf to gdb. However, after using dissolve, the issue was resolved and it copies fast now.
