To: dev@ignite.apache.org Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hello, The link [1] is the issue with Persistence for text indices. AFAIK, the issue is very difficult with their implementation and has a doubtful performance improvement. One of the most obvious disadvantages of persisted Lucene indexes can be that they will dramatically slow down the node start time. So, probably, better to keep them in-memory only.
