class RoomStreamToken:
"""Tokens are positions between events. The token "s1" comes after event 1.
s0 s1
| |
[0] ▼ [1] ▼ [2]
Tokens can either be a point in the live event stream or a cursor going
through historic events.
When traversing the live event stream, events are ordered by
`stream_ordering` (when they arrived at the homeserver).
When traversing historic events, events are first ordered by their `depth`
(`topological_ordering` in the event graph) and tie-broken by
`stream_ordering` (when the event arrived at the homeserver).
If you're looking for more info about what a token with all of the
underscores means, ex.
`s2633508_17_338_6732159_1082514_541479_274711_265584_1`, see the docstring
for `StreamToken` below.
---
Live tokens start with an "s" followed by the `stream_ordering` of the event
that comes before the position of the token. Said another way:
`stream_ordering` uniquely identifies a persisted event. The live token
means "the position just after the event identified by `stream_ordering`".
An example token is:
s2633508
---
Historic tokens start with a "t" followed by the `depth`
(`topological_ordering` in the event graph) of the event that comes before
the position of the token, followed by "-", followed by the
`stream_ordering` of the event that comes before the position of the token.
An example token is:
t426-2633508
---
There is also a third mode for live tokens where the token starts with "m",
which is sometimes used when using sharded event persisters. In this case
the events stream is considered to be a set of streams (one for each writer)
and the token encodes the vector clock of positions of each writer in their
respective streams.
The format of the token in such case is an initial integer min position,
followed by the mapping of instance ID to position separated by '.' and '~':
m{min_pos}~{writer1}.{pos1}~{writer2}.{pos2}. ...
The `min_pos` corresponds to the minimum position all writers have persisted
up to, and then only writers that are ahead of that position need to be
encoded. An example token is:
m56~2.58~3.59
Which corresponds to a set of three (or more writers) where instances 2 and
3 (these are instance IDs that can be looked up in the DB to fetch the more
commonly used instance names) are at positions 58 and 59 respectively, and
all other instances are at position 56.
Note: The `RoomStreamToken` cannot have both a topological part and an
instance map.
