getStreamTables

getStreamTables([option=0])

Get the information of specified stream tables.

option (optional) is an integral scalar indicating the type of the stream table to be obtained. It can take the following values:

• 0: all stream tables;

• 1: persisted stream tables;

• 2: non-persisted stream tables;

It returns a table containing the following columns:

• name: Table name.
• shared: Whether the table is shared.
• persisted: Whether the table is persisted.
• cachePurgeEnabled: Whether cache purge is enabled.
• loaded: Whether the table is loaded into memory.
• columns: The number of columns.
• rowsInMemory: The number of rows in memory.
• totalRows: The total number of rows.
• memoryUsed: Memory used (in bytes).
• accessControlEnabled: Whether access control has been configured for the table using addAccessControl. A value of true indicates that access control has been enabled, while false indicates that it has not been configured.

Note: If the persisted table has not been loaded to memory, only "name", "persisted", and "loaded" columns are returned. Null values are returned for the rest of columns.
