class InMemoryCatalog extends ExternalCatalog

An in-memory (ephemeral) implementation of the system catalog.

This is a dummy implementation that does not require setting up external systems. It is intended for testing or exploration purposes only and should not be used in production.

All public methods should be synchronized for thread-safety.

  4. def alterDatabase(dbDefinition: CatalogDatabase): Unit

    Alter a database whose name matches the one specified in dbDefinition, assuming the database exists.

    Alter a database whose name matches the one specified in dbDefinition, assuming the database exists.

    Note: If the underlying implementation does not support altering a certain field, this becomes a no-op.

  7. def alterTable(tableDefinition: CatalogTable): Unit

    Alter a table whose database and name match the ones specified in tableDefinition, assuming the table exists.

    Alter a table whose database and name match the ones specified in tableDefinition, assuming the table exists. Note that, even though we can specify database in tableDefinition, it's used to identify the table, not to alter the table's database, which is not allowed.

    Note: If the underlying implementation does not support altering a certain field, this becomes a no-op.

  8. def alterTableDataSchema(db: String, table: String, newDataSchema: StructType): Unit

    Alter the data schema of a table identified by the provided database and table name.

    Alter the data schema of a table identified by the provided database and table name. The new data schema should not have conflict column names with the existing partition columns, and should still contain all the existing data columns.

    db

    Database that table to alter schema for exists in

    table

    Name of table to alter schema for

    newDataSchema

    Updated data schema to be used for the table.

  9. def alterTableStats(db: String, table: String, stats: Option[CatalogStatistics]): Unit

    Alter the statistics of a table.

    Alter the statistics of a table. If stats is None, then remove all existing statistics.

    List the names of all partitions that belong to the specified table, assuming it exists.

    List the names of all partitions that belong to the specified table, assuming it exists.

    For a table with partition columns p1, p2, p3, each partition name is formatted as p1=v1/p2=v2/p3=v3. Each partition column name and value is an escaped path name, and can be decoded with the ExternalCatalogUtils.unescapePathName method.

    The returned sequence is sorted as strings.

    A partial partition spec may optionally be provided to filter the partitions returned, as described in the listPartitions method.

    partialSpec

    List the metadata of all partitions that belong to the specified table, assuming it exists.

    A partial partition spec may optionally be provided to filter the partitions returned. For instance, if there exist partitions (a='1', b='2'), (a='1', b='3') and (a='2', b='4'), then a partial spec of (a='1') will return the first two only.
