Anoma.Node.Tables (Anoma v0.32.0)

Summary

Types

table_spec()

A table is typed by a tuple where the first element is the table name, and the second one is a list of keys (i.e., columns).

table_specs()

a list of table specs

Functions

clear_table(table_name)

I clear out the given table.

copy_table_rows(source_table, target_table, cont \\ nil)
create_local_schema()
create_table(name, fields)
create_tables(table_list)
duplicate_table(source_table, target_table)

I duplicate a given table's content to a new table. If the new table does not exist, it is created.

has_data?(node_id)
initialize_storage()

I initialize the mnesia storage for this entire vm.

initialize_tables_for_node(node_id)

I initialize the tables for a given node id. I do this by creating all tables in the mnesia storage.

node_table_name(node_id, name)

Given an atom as table name, I create a node-specific name based on that.

table_blocks(node_id)

I return the table name for the given node its blocks.

table_commitment_tree(node_id \\ "no_node")

I return the table name for the given node its commitment tree. I can be called without a node id too. In that case I use "no_node" as node id.

table_events(node_id)

I return the table name for the given node its event table.

table_exists?(table)

Check if the given table name exists.

table_intents(node_id)

I return the table name for the intents table.

table_updates(node_id)

I return the table name for the given node its updates.

table_values(node_id)

I return the table name for the given node its values.

tables_exist?(table_names)

Check if a given list of tables exists.

table_commitment_tree(node_id \\ "no_node")

@spec table_commitment_tree(String.t()) :: atom()

I return the table name for the given node its commitment tree. I can be called without a node id too. In that case I use "no_node" as node id.

Link to this function

table_exists?(table)

@spec table_exists?(atom()) :: boolean()

Check if the given table name exists.

Run inside transaction.

  | {:error, :partial_exist | :none_exist | :failed_to_check_tables}

Check if a given list of tables exists.

This function takes a list of tables to avoid waiting for tables multiple times.
