=head1 NAME

Rethinkdb::Query::Table - RethinkDB Query Table

=head1 SYNOPSIS

=head1 DESCRIPTION

L is a type of query that represents a table in a
database. This classes contains methods to interact with said table.

=head1 ATTRIBUTES

L implements the following attributes.

=head2 name

  my $table = r->db('comics')->table('superheros');
  say $table->name;

The name of the table.

=head1 METHODS

L implements the following methods.

=head2 create

  r->db('test')->table('dc_universe')->create->run;

Create this table. A RethinkDB table is a collection of JSON documents.

If successful, the operation returns an object: C<< {created => 1} >>. If a
table with the same name already exists, the operation returns a
C.

B that you can only use alphanumeric characters and underscores for the
table name.

=head2 drop

  r->db('test')->table('dc_universe')->drop->run(conn)

Drop this table. The table and all its data will be deleted.

If successful, the operation returns an object: C<< {dropped => 1} >>. If the
specified table doesn't exist a C is returned.

=head2 index_create

  r->table('comments')->index_create('post_id')->run;

Create a new secondary index on a table.

=head2 index_drop

  r->table('dc')->index_drop('code_name')->run;

Delete a previously created secondary index of this table.

=head2 index_list

  r->table('marvel')->index_list->run;

List all the secondary indexes of this table.

=head2 index_rename

  r->table('marvel')->index_rename('heroId', 'awesomeId')->run;

Rename an existing secondary index on a table. If the optional argument
C is specified as C, a previously existing index with the new
name will be deleted and the index will be renamed. If C is C
(the default) an error will be raised if the new index name already exists.

=head2 index_status

  r->table('test')->index_status->run;
  r->table('test')->index_status('timestamp')->run;

Get the status of the specified indexes on this table, or the status of all
indexes on this table if no indexes are specified.

=head2 index_wait

  r->table('test')->index_wait->run;
  r->table('test')->index_wait('timestamp')->run;

Wait for the specified indexes on this table to be ready, or for all indexes on
this table to be ready if no indexes are specified.

=head2 changes

  my $stream = r->table('games')->changes(sub {
    my $item;
    say Dumper $_;
  })->run;

Return an infinite stream of objects representing changes to a table. Whenever
an C, C, C or C is performed on the table, an
object of the form C<< {'old_val' => ..., 'new_val' => ...} >> will be appended
to the stream. For an C, C will be C, and for a
C, C will be C.

=head2 insert

  r->table('posts')->insert({
    id => 1,
    title => 'Lorem ipsum',
    content => 'Dolor sit amet'
  })->run;

Insert documents into a table. Accepts a single document or an array of
documents.

=head2 sync

L ensures that writes on a given table are written to permanent storage.
Queries that specify soft durability C<< {durability => 'soft'} >> do not give
such guarantees, so sync can be used to ensure the state of these queries. A
call to sync does not return until all previous writes to the table are
persisted.

=head2 get

  r->table('posts')->get('a9849eef-7176-4411-935b-79a6e3c56a74')->run;

Get a document by primary key.

If no document exists with that primary key, L will return C.

=head2 get_all

  r->table('marvel')->get_all('man_of_steel', { index => 'code_name' })->run;

Get all documents where the given value matches the value of the requested
index.

=head2 between

  r->table('marvel')->between(10, 20)->run;

Get all documents between two keys. Accepts three optional arguments: C,
C, and C. If C is set to the name of a
secondary index, L will return all documents where that index's value
is in the specified range (it uses the primary key by default). C
or C may be set to open or closed to indicate whether or not to
include that endpoint of the range (by default, C is closed and
C is open).

=head2 get_intersecting

  r->table('geo')
    ->get_intersecting(
    r->circle( [ -122.423246, 37.770378359 ], 10, { unit => 'mi' } ),
    { index => 'location' } )->run;

Get all documents where the given geometry object intersects the geometry
object of the requested geospatial index.

=head2 get_nearest

  r->table('geo')->get_nearest(
    r->point( -122.422876, 37.777128 ),
    { index => 'location', max_dist => 5000 }
  )->run;

Get all documents where the specified geospatial index is within a certain
distance of the specified point (default 100 kilometers).

=head2 config

  r->table('marvel')->config->run;

Query (read and/or update) the configurations for individual tables.

=head2 rebalance

  r->table('marvel')->rebalance->run;

Rebalances the shards of a table.

=head2 reconfigure

  r->table('marvel')->reconfigure({ shards => 2, replicas => 1 })->run;
  r->table('marvel')->reconfigure(
    {
      shards              => 2,
      replicas            => { wooster => 1, wayne => 1 },
      primary_replica_tag => 'wooster'
    }
  )->run;

Reconfigure a table's sharding and replication.

=head2 status

  r->table('marvel')->status->run;

Return the status of a table. The return value is an object providing
information about the table's shards, replicas and replica readiness states

=head2 wait

  r->table('marvel')->wait->run;

Wait for a table to be ready. A table may be temporarily unavailable
after creation, rebalancing or reconfiguring. The L command
blocks until the given table is fully up to date.
