Examples of com.odiago.flumebase.exec.SymbolTable

com.odiago.flumebase.exec.SymbolTable
Holds all the symbol definitions available to the user in the current session. e.g., named streams, flows, etc. Also contains the metadata associated with each one. This may be stored locally in memory (for a transient symbol table) or backed by a database metastore, etc. SymbolTables may shadow other symbol tables to provide localized contexts. For example, within a SELECT statement, the symbol table contains the column aliases present in the statement.
