When to use dissolve in a feature class?
Dissolve can create very large features in the output feature class. This is especially true when there is a small number of unique values in the Dissolve Field (s) parameter or when dissolving all features into a single feature.
Are there any problems with the dissolve function?
Very large features may cause processing or display problems or have poor performance when drawn on a map or when edited. Problems may also occur if the dissolve output created a feature at the maximum size on one machine, and this output was moved to a machine with less available memory.
Can a dissolve run reduce the output of a previous dissolve run?
Running Dissolve on the output of a previous dissolve run will rarely reduce the number of features in the output when the original processing divided and processed the inputs using adaptive tiling.

How does the dissolve process work in ArcGIS Pro?
To prevent this, Dissolve may divide and process the input features using an adaptive tiling algorithm. To determine the features that have been tiled, run the Frequency tool on the result of this tool, specifying the same fields used in the dissolve process for the Frequency Field (s) parameter.
When to use the dissolve function in Python?
DISSOLVE_LINES — Lines are dissolved into a single feature. This is the default. UNSPLIT_LINES — Lines are only dissolved when two lines have an end vertex in common. The following Python window script demonstrates how to use the Dissolve function in immediate mode. The following stand-alone script demonstrates how to use the Dissolve function.
