Marco Neumann 801cf08be7 feat: auto-creation of sequencers by write buffer 
For Kafka, that basically means that we create a topic if it doesn't
exist yet.

Closed #2455.
Fixes #2189.

Marco Neumann 2ea3b600d0 test: harden `assert_reader_content` a bit 
- entries should be sorted by the stream, there is no need to sort the
  results
- ensure that there are no leftover entries in the stream by asserting
  that it is "pending"

Marco Neumann a63eb53ac5 feat: forward connection config to Kafka write buffer 2021-09-02 16:53:31 +02:00
Marco Neumann ecf1f99ddb refactor: more flexible writer buffer config 
This allows:

- different types (instead of guessing through the connection URL)
- sequencer counts (not used yet but will be by #2455)
- extensible configs (e.g. to configure Kafka in a more granular way,
  not wired up yet)
- future extensions (since we use a message now instead of a single
  string)

**BREAKING: This requires changes for deployed systems / existing DBs!**

Marco Neumann f81885c172 fix: limit kafka consumer queue to 10MB 
I think that while this value limits the maximum memory consumption, it
is too optimistic.
 2021-08-20 09:55:49 +02:00
Marco Neumann 6c0cefded3 fix: limit kafka consumer queue to 100MB 
By default the queue will be filled to up to 1GB which makes finding
memory leaks quite hard.

build: use new rustdoc lint name (#2261) 
* fix: nocache feature code rot

The MBChunk::snapshot code when using the "nocache" option no longer
compiles - this commit updates it to match the not(nocache) code.

* build: use updated broken_intra_doc_links name

The broken_intra_doc_links lint was renamed
rustdoc::broken_intra_doc_links

Marco Neumann b0663a0337 feat: disallow multiple write buffer streams and seeking while streams

Marco Neumann 592424c896 refactor: use one stream per sequencer/partition 
Advantages are:

- for large DBs w/ many partitions we can ingest data in-parallel
- on top of this change we can implement per-sequencer seeking, which is
  required for replay

Carol (Nichols || Goulding) 7301268b4f fix: Increase the internal librdkafka producer queue size 
Given that we've increased the max message size by a factor of 10, also
increase the internal producer queue max size by a factor of 10 to
reduce the number of retries needed to successfully enqueue messages to
Kafka.

Connects to #2007.

Carol (Nichols || Goulding) fa3a2db0d3 fix: Retry adding Kafka messages to queue forever

Marco Neumann b5428e53a5 refactor: write buffer testing + better mocking 
This refactors the write buffer a bit for:

- **Testing:** Add generic tests for the Kafka and the mocking
  implementation. The same interface can be used easily add new
  implementations (e.g. via Redis, filesystem, ...).
- **Partition on Write:** The caller of the writer operation must now
  specify the partition/sequencer ID. The implicit partitioning of the
  Kafka writer would have lead to broken data since we must never spill
  entries w/ the same primary key over multiple partitions. At the
  moment we will only use partition 0 but we can easily implement
  better logic in the future.
- **Improved Mocking:** The mocked implementation now simulates a system
  that feels more real. Especially the handling around multiple streams
  and "write while read" has been improved. This will be helpful for
  testing and for new features like seeking (during replay). A solid
  realistic mock also helps us to ensure that the tests using the mock
  do not rely on unrealistic behavior too much.
