Understanding the splitting and balancing
processes
Splitting and balancing are two background processes that perform the maintenance of an
entire cluster. The splitting process prevents chunks from growing too large and controls
the size of each chunk. When a chunk size grows larger than the defined chunk size, the en-
gine splits that chunk in half.
The default size of the chunk is 64 MB, but you can change the size by overwriting config-
urations. Suppose a chunk grows more than 64 MB, the splitting processes make two new
chunks at half of the size of the parent chunk.
The following diagram shows the procedure of dividing a chunk into new chunks:
