What is Chunking?
Chunked data are written in chunks of user-defined size. |
| 18.1 |
Choosing Chunksizes
How do you pick chunksizes? |
| 18.2 |
Setting the Chunksizes in NetCDF-4
Set the chunksizes for variables in netCDF-4 file with nc_def_var_chunking(). |
| 18.3 |
Example of Setting Chunksizes in Fortran 90
In this example code (from nf_test/f90tst_vars.f90) the chunksize is set for a 2-dimensional variable in Fortran 90. |

The Cache in NetCDF-4
The cache is used when reading or writing data. Set the cache size correctly for each variable to improve performance. |
| 18.5 |
Setting the Cache in NetCDF-4
Set the cache for a variable with the nc_var_set_cache function. |
| 18.6 |
Per-Variable Compression in NetCDF-4
Chunked variables in netCDF-4 files may use on-the-fly compression with zlib. |

Per-Variable Compression in NetCDF-4
This example shows how to set the compression level for variables. |

Contiguous Variables
A contiguous variable is stored as one long array in the file. |
| 18.11 |
Using Contiguous Variables
Use the nc_def_var_chunking function to make a variable contiguous. |
