Module rsdb::c
[−]
[src]
C-compatible API for the lock-free log-structured B+tree.
Functions
rsdb_cas⚠ |
Compare and swap. Returns 1 if successful, 0 if unsuccessful. Otherwise sets actual_val and actual_vallen to the current value, which must be freed using rsdb_free_buf by the caller if non-null. actual_val will be null and actual_vallen 0 if the current value is not set. |
rsdb_close⚠ |
Close a rsdb lock-free log-structured tree. |
rsdb_config_flush_every_ms⚠ |
Set the configured IO buffer flush interval in milliseconds. |
rsdb_config_set_cache_capacity⚠ |
Set the configured cache capacity in bytes. |
rsdb_config_set_path⚠ |
Set the configured file path. The caller is responsible for freeing the path string after calling this (it is copied in this function). |
rsdb_config_snapshot_after_ops⚠ |
Set the configured snapshot operation threshold. |
rsdb_config_use_compression⚠ |
Configure the use of the zstd compression library. |
rsdb_create_config⚠ |
Create a new configuration. |
rsdb_del⚠ |
Delete the value of a key. |
rsdb_destroy_config⚠ |
Destroy a configuration. |
rsdb_free_buf⚠ |
Free a buffer originally allocated by RSDB. |
rsdb_free_iter⚠ |
Free an iterator. |
rsdb_get⚠ |
Get the value of a key. Caller is responsible for freeing the returned value with rsdb_free_buf if it's non-null. |
rsdb_iter_next⚠ |
Get they next kv pair from an iterator. Caller is responsible for freeing the key and value with rsdb_free_buf. Returns 0 when exhausted. |
rsdb_open⚠ |
Open a rsdb lock-free log-structured tree. |
rsdb_scan⚠ |
Iterate from a starting key. Caller is responsible for freeing the returned iterator with rsdb_free_iter. |
rsdb_set⚠ |
Set a key to a value. |
