The examples above show storing using put , which write the HDF5 to PyTables in a fixed array format, called the fixed format. These types of stores are are not appendable once written (though you can simply remove them and rewrite). Nor are they queryable they must be retrieved in their entirety. They also do not support dataframes with non-unique column names. The fixed format stores offer very fast writing and slightly faster reading than table stores. This format is specified by default when using put or to_hdf or by format='fixed' or format='f'
[a] This option is dynamic, but only the server should set this information. You should not set the value of this variable manually.
This is a very new feature of pandas. We intend to provide certain optimizations in the io of the msgpack data. Since this is marked as an EXPERIMENTAL LIBRARY, the storage format may not be stable until a future release.
This variable sets the maximum size to which user-created MEMORY tables are permitted to grow. The value of the variable is used to calculate MEMORY table MAX_ROWS values. Setting this variable has no effect on any existing MEMORY table, unless the table is re-created with a statement such as CREATE TABLE or altered with ALTER TABLE or TRUNCATE TABLE . A server restart also sets the maximum size of existing MEMORY tables to the global max_heap_table_size value.
Data is ordered (on the disk) in terms of the indexables . Here 8767 s a simple use case. You store panel-type data, with dates in the major_axis and ids in the minor_axis . The data is then interleaved like this:
This variable controls whether the server sends the UPN in the initial challenge. By default, the variable is enabled. For security reasons, it can be disabled to avoid sending the server's account name to a client in clear text. If the variable is disabled, the server always sends a 5x55 byte in the first challenge, the client does not specify targetName , and as a result, NTLM authentication is used.
