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.
