0.11.3

Overview

This is a bugfix release. Several cases of pagination using select
with after was fixed or improved. Warning has been added to
potentially long select and count calls. Storage select errors
were reworked to be consistent with other calls errors.

Breaking changes

There are no breaking changes in the release.

New features

• Optimize crud.select() without conditions and with
  after (PR #295).

• A critical log entry containing the current stack traceback is
  created upon potentially long select and count calls —
  an user can explicitly request a full scan through by passing
  fullscan=true to select or count options table argument
  in which case a log entry will not be created (#276).

Bugfixes

• Make select error description more informative when merger
  built-in module or tuple-merger external module is used
  in case of disabled/uninit storage (#229).

• crud.select() if a condition is '<=' and it's
  value < after (PR #295).

  Suppose we have a non-unique secondary index by the field age
  field and a space:

  tarantool> crud.select('developers', nil, {first = 10})
  ---
  - metadata: [{'name': 'id', 'type': 'unsigned'},
      {'name': 'bucket_id', 'type': 'unsigned'},
      {'name': 'name', 'type': 'string'},
      {'name': 'surname', 'type': 'string'},
      {'name': 'age', 'type': 'number'}]
    rows:
    - [1, 477, 'Alexey', 'Adams', 20]
    - [2, 401, 'Sergey', 'Allred', 27]
    - [3, 2804, 'Pavel', 'Adams', 27]
    - [4, 1161, 'Mikhail', 'Liston', 27]
    - [5, 1172, 'Dmitry', 'Jacobi', 27]
    - [6, 1064, 'Alexey', 'Sidorov', 31]
  - null
