ES 413 Request too large error with testnet-6.1.0

[abitmore]

Bug Description

A Testnet node running the test-6.1.0 tag is unable to sync if

• the elasticsearch plugin is enabled, and
• both the elasticsearch-operation-object and the elasticsearch-operation-string startup options are true, and
• even elasticsearch-bulk-replay is set to 200 (whose default value is 10000), and
• all other options are default.

Error messages:

handle_bulk_response ] 413 error: Request too large. Can be low disk space. elasticsearch.cpp:56

It is caused by transfers with huge memos. The size of each transfer is around 400 KB in the serialized form, and the size of the corresponding request to ES is around 1.5 MB in 2 lines. With elasticsearch-bulk-replay = 200, the total request size is around 150 MB. But unfortunately the default maximum request size allowed by ES is 100 MB, so we got the error.

The node is able to sync if elasticsearch-bulk-replay is changed to 100.
