CustomTableResolver, MetaStore

All Known Implementing Classes:

AvroTableProvider, BigQueryTableProvider, BigtableTableProvider, DataGeneratorTableProvider, DataStoreV1TableProvider, FullNameTableProvider, GenerateSequenceTableProvider, InMemoryMetaStore, InMemoryMetaTableProvider, KafkaTableProvider, MongoDbTableProvider, ParquetTableProvider, PubsubLiteTableProvider, PubsubTableProvider, ReadOnlyTableProvider, SchemaIOTableProviderWrapper, TestTableProvider, TextTableProvider

A TableProvider handles the metadata CRUD of a specified kind of tables.
So there will be a provider to handle textfile(CSV) based tables, there is a provider to handle MySQL based tables, a provider to handle Casandra based tables etc.
Note: all implementations marked with @AutoService(TableProvider.class) are automatically loaded by CLI or other cases when JdbcDriver is used with default connection parameters.
