| #define CHERT_DEFAULT_BLOCK_SIZE 8192 |
The default block size to use in a B-tree table.
If this is changed, be sure to update the API documentation correspondingly.

| typedef unsigned int chert_revision_number_t |
A type used to store a revision number for a table.
A table's revision number increases monotonically, incrementing by one each time a modification is applied to the table.
FIXME: ensure that this is of a suitable minimum size - 32 bits is satisfactory in most cases, but in extreme cases could cause the revision number to roll over after a few years. It would be better to use 64 bits (and / or to ensure that rolling over causes no problem).
Definition at line 39 of file chert_types.h.
| typedef unsigned long long chert_tablesize_t |
A type used to store the number of entries in a table.
Again, this must be of suitable minimum size.
