light dal package

banner.connection:

• Connection(Object):

  • ABS class

• CacheConnection(Connection):

  • ABS class

• MySqlConnection(Connection)(host, user, passwd, db, ssl_key, ssl_cert, name):

  • Create Connection object compatible with banner.queries

  • raises MySQLError for bad connection

• RedisConnection(CacheConnection)(host, port, passwd, db, ssl_key, ssl_cert, name, ttl):

  • Create CacheConnection object compatible with banner.queries

• connections(conns: Dict[str, Connection] = {}):

  • Getter/Setter for known(default) Connections dict

• cache_connection(con: CacheConnection = None):

  • Getter/Setter for known(default) CacheConnection

banner.queries:

• simple_query(query: str, connection=None, cache_connection=None, ttl=None) -> pd.DataFrame:

  • run a simple string query for Connection

  • connection=None try to get first known connection, raise KeyError if None found

  • Cache the result if cache_connection or banner.connection.cache_connection exists (ttl if provided otherwise use cache_connection.ttl)

• neware_query(device: int, unit: int, channel: int, test: int, connection: Union[Connection, str] = None, cache_connection=None, ttl=None, raw=False, dqdv=False):

  • query Connection for device, unit, channel, test

  • connection=None try to get first known connection, raise KeyError if None found

  • raw=True return data as saved in the db

  • raw=False compute temp, voltage, current aswell as grouping by auxchl_id

  • dqdv=True -> banner.neware.calc_dq_dv

  • Cache the result if cache_connection or banner.connection.cache_connection exists (ttl if provided otherwise use cache_connection.ttl)

  • raises Type err if no data exists

• neware_query_by_test(table: str, cell: int, test: int, connection: Union[Connection, str] = None, cache_connection=None, ttl=None, raw=False, dqdv=False):

  • query Connection for device, unit, channel, test, as well as the connection storing the data

  • connection=None try to get first known connection, raise KeyError if None found

  • Try merging neware_cache_query for given test

  • raw=True return data as saved in the db

  • raw=False compute temp, voltage, current aswell as grouping by auxchl_id

  • dqdv=True -> banner.neware.calc_dq_dv

  • Cache the result if cache_connection or banner.connection.cache_connection exists (ttl if provided otherwise use cache_connection.ttl)

  • returns neware_query for result values, the connection has to be an entry in connections()

  • raises Type err if no data exists

• describe_table(table, connection: Union[Connection, str] = None)

  • Returns a series of table columns

  • connection=None try to get first known connection, raise KeyError if None found

• describe(table, connection: Union[Connection, str] = None)

  • Returns a series of db tables

  • connection=None try to get first known connection, raise KeyError if None found

banner.neware:

-calc_neware_cols(data: pd.DataFrame):

• calculate neware columns for a valid neware DataFrame

• calc_dq_dv(data: pd.DataFrame, raw=False):

  • Calculate DQ/DV for a valid neware df

  • raw=False: remove outliers

• merge_cache(data: pd.DataFrame, cache_data: pd.DataFrame):

  • Given data(neware df), cache_data(neware_cache df), tries to merge cache_data into data

  • ** Raises TypeError and Index Error**
